Is Big Bang a Jewish issue? Comments on Bereshit

 

Torah portion comments  Bereshit 1st cycle

 For video: https://youtu.be/T-JTX8A3NCE?t=7105


 

1)     Is Big Bang a Jewish issue?

Notice that we have two accounts of creation: Ch 1 and Ch 2

a)      Ch 1, orderly, builds up one upon the other, systematic, culminates with human, and Shabbat-state of perfection.

b)     Ch 2,

A} sloppy editing, patched together hoping no one will notice?

 

 

בראשית ברא אֵין הַמִּקְרָא הַזֶּה אוֹמֵר אֶלָּא דָּרְשֵׁנִי, כְּמוֹ שֶׁדְּרָשׁוּהוּ רַבּוֹתֵינוּ בִּשְׁבִיל הַתּוֹרָה שֶׁנִקְרֵאת רֵאשִׁית דַּרְכּוֹ (משלי ח'), וּבִשְׁבִיל יִשְׂרָאֵל שֶׁנִקְרְאוּ רֵאשִׁית תְּבוּאָתוֹ (ירמיה ב'); וְאִם בָּאתָ לְפָרְשׁוֹ כִּפְשׁוּטוֹ, כָּךְ פָּרְשֵׁהוּ בְּרֵאשִׁית בְּרִיאַת שָׁמַיִם וָאָרֶץ, וְהָאָרֶץ הָיְתָה תֹהוּ וָבֹהוּ וְחֹשֶׁךְ וַיֹּאמֶר אֱלֹהִים יְהִי אוֹר וְלֹא בָא הַמִּקְרָא לְהוֹרוֹת סֵדֶר הַבְּרִיאָה לוֹמַר שֶׁאֵלּוּ קָדְמוּ, שֶׁאִם בָּא לְהוֹרוֹת כָּךְ, הָיָה לוֹ לִכְתֹּב בָּרִאשׁוֹנָה בָּרָא אֶת הַשָּׁמַיִם וְגוֹ' שֶׁאֵין לְךָ רֵאשִׁית בַּמִּקְרָא שֶׁאֵינוֹ דָבוּק לַתֵּבָה שֶׁלְּאַחֲרָיו. .

. עַל כָּרְחֲךָ לֹא לִמֵּד הַמִּקְרָא סֵדֶר הַמֻּקְדָמִים וְהַמְאֻחָרִים כְּלוּם:

אין מוקדם ומאחר במקרא

בראשית ברא IN THE BEGINNING GOD CREATED — This verse calls aloud for explanation in the manner that our Rabbis explained it: God created the world for the sake of the Torah which is called (Proverbs 8:22) “The beginning (ראשית) of His (God’s) way”, and for the sake of Israel who are called (Jeremiah 2:3) “The beginning (ראשית) of His (God’s) increase’’. If, however, you wish to explain it in its plain sense, explain it thus: At the beginning of the Creation of heaven and earth when the earth was without form and void and there was darkness, God said, “Let there be light”. The text does not intend to point out the order of the acts of Creation — to state that these (heaven and earth) were created first; for if it intended to point this out, it should have written 'בראשונה ברא את השמים וגו “At first God created etc.”

 

a further proof that the heavens and earth were not the first thing created is that the heavens were created from fire (אש) and water (מים), from which it follows that fire and water were in existence before the heavens. Therefore you must admit that the text teaches nothing about the earlier or later sequence of the acts of Creation.

 

Maimonides argued that if science proved a point that did not contradict any fundamentals of faith, then the finding should be accepted and scripture should be interpreted accordingly.[14] For example, in discussing Plato's view that the universe has existed literally forever, he argued that there was no convincing rational proof one way or the other, so that he (Maimonides) was free to accept, and therefore did accept, the literal biblical view that the universe came into being at a definite time; but that had Plato's theory been convincing enough with sufficient scientific proof he would have been able to reinterpret Genesis accordingly.

 

One of the most popular theories about the development of the Universe-The Big Bang Theory.

We can make a claim to having thought of it first, in the Kabbalah of Rabbi Isaac Luria, Ari Hakadosh: tzimtzum, contraction into a single point, expansion form that contraction , channels of energy out of that)kelim-vessels- to “ shvirat hakelim”- cataclysmic shattering of these channels of energy, giving rise to the world as we know it.

 

However- we can ask, from a Jewish perspective-Does it Matter? Not for a lack of Jewish physicists- https://en.wikipedia.org/wiki/Category:Jewish_physicists

 

But:

https://www.sefaria.org/Chagigah.11b.6?vhe=William_Davidson_Edition_-_Vocalized_Aramaic&lang=bi&with=all&lang2=en

 

Forbidden Sex- to three; Maaseh Merkabah- to two, Maaseh bereshit- to only one.

כׇּל הַמִּסְתַּכֵּל בְּאַרְבָּעָה דְּבָרִים, רָתוּי לוֹ כְּאִילּוּ לֹא בָּא לָעוֹלָם: מָה לְמַעְלָה, מָה לְמַטָּה, מָה לְפָנִים, וּמָה לְאָחוֹר. וְכׇל שֶׁלֹּא חָס עַל כְּבוֹד קוֹנוֹ, רָתוּי לוֹ שֶׁלֹּא בָּא לָעוֹלָם. Whoever looks at four matters, it would have been better for him had he never entered the world: what is above what is below, what was before, and what  after. And anyone who has no concern for the honor of his Maker, deserves to have never come to the world.

 

 

Mishna and Gemara: Don’t even think of going there.

 

Why end speculation?

 

 

 

II. Why are there two ways Adam is created?

1)     Elegant, magisterial, the epitome of creation.

וַיֹּ֣אמֶר אֱלֹהִ֔ים נַֽעֲשֶׂ֥ה אָדָ֛ם בְּצַלְמֵ֖נוּ כִּדְמוּתֵ֑נוּ וְיִרְדּוּ֩ בִדְגַ֨ת הַיָּ֜ם וּבְע֣וֹף הַשָּׁמַ֗יִם וּבַבְּהֵמָה֙ וּבְכׇל־הָאָ֔רֶץ וּבְכׇל־הָרֶ֖מֶשׂ הָֽרֹמֵ֥שׂ עַל־הָאָֽרֶץ׃ And God said, “Let us make humankind in our image, after our likeness. They shall rule the fish of the sea, the birds of the sky, the cattle, the whole earth, and all the creeping things that creep on earth.”

וַיִּבְרָ֨א אֱלֹהִ֤ים׀אֶת־הָֽאָדָם֙ בְּצַלְמ֔וֹ בְּצֶ֥לֶם אֱלֹהִ֖ים בָּרָ֣א אֹת֑וֹ זָכָ֥ר וּנְקֵבָ֖ה בָּרָ֥א אֹתָֽם׃ And God created humankind in the divine image,
creating it in the image of God—
creating them male and female

https://www.sefaria.org/Genesis.1.26-27?lang=bi&with=all&lang2=en#:~:text=%D7%95%D6%B7%D7%99%D6%BC%D6%B9%D6%A3%D7%90%D7%9E%D6%B6%D7%A8%20%D7%90%D6%B1%D7%9C%D6%B9%D7%94%D6%B4%D6%94%D7%99%D7%9D%20%D7%A0%D6%B7%D6%BD%D7%A2%D6%B2%D7%A9%D7%82%D6%B6%D6%A5%D7%94,%D7%95%D6%BC%D7%A0%D6%B0%D7%A7%D6%B5%D7%91%D6%B8%D6%96%D7%94%20%D7%91%D6%BC%D6%B8%D7%A8%D6%B8%D6%A5%D7%90%20%D7%90%D6%B9%D7%AA%D6%B8%D6%BD%D7%9D%D7%83

 

 

2)     A more “ hands on” affair:

וַיִּ֩יצֶר֩ יְהֹוָ֨ה אֱלֹהִ֜ים אֶת־הָֽאָדָ֗ם עָפָר֙ מִן־הָ֣אֲדָמָ֔ה וַיִּפַּ֥ח בְּאַפָּ֖יו נִשְׁמַ֣ת חַיִּ֑ים וַֽיְהִ֥י הָֽאָדָ֖ם לְנֶ֥פֶשׁ חַיָּֽה׃God יהוה formed the Human blowing into his nostrils the breath of life: the Human became a living being.

https://www.sefaria.org/Genesis.2.6-7?lang=bi&with=all&lang2=en#:~:text=of%20the%20earth%E2%80%94-,7,nostrils%20the%20breath%20of%20life%3A%20the%20Human%20became%20a%20living%20being.,-8

This is a more complicated entity-intelligent( names animals), is given instructions, is lonely! Gets in trouble- the beautiful perfection of chapter one is disturbed by Adam of chapter 2.

Why?

From Rav Yosef Soloveitchik-Lonely Man of Faith(excerpts from a very long essay)

I want to point out four major discrepancies between these

two accounts.

 

1) In the story of the creation of Adam the first, it is told that

the latter was created in the image of God, betselem elokim, while ·

nothing is said about how his body was formed. In the account

of the creation of Adam the second, it is stated that he

was fashioned from the dust of the ground and God breathed

into his nostrils the breath of life.

2) Adam the first received the mandate from the Almighty

to fill the earth and subdue it, milo et Haaretz v kivshuha. Adam

the second was charged with the duty to cultivate the garden and

to keep it, le-ovda u leshamra

 

3) In the story of Adam the first, both male and female were

created concurrently, while Adam the second emerged alone, with

Eve appearing subsequently as his helpmate and complement.

4) Finally, and this is a discrepancy of which Biblical criticism

has made so much, while in the first account only the name of

E-lohim, appears, in the second, E-lohim is used in conjunction

with the Tetragrammaton.

 

There is no doubt that the term "image of. God" in the first

account refers to man's inner charismatic endowment as a creative

being. Man's likeness to God expresses itself in man's striving and ability to become a creator

 

Therefore, Adam the first is interested in just a single

aspect of reality and asks one question only - "How does the

cosmos function?" He is not fascinated by the question, "Why

, does the cosmos function at all?" nor is he interested in the question,

"What is its essence?" He is only curious to know how it

works…. Adam the first is overwhelmed by one quest, namely,.to harness

and dominate the elemental natural forces and to put them at his

, disposal. This practical interest arouses his will to learn the secrets

of nature. He is completely utilitarian as far as motivation, teleology, design and methodology are concerned.

 

Man reaching for the distant stars is acting in harmony with his nature which was created,

willed, and directed by his Maker. It is a manifestation of obedience to rather than rebellion against God.

 

Adam the second

responds to the call of the cosmos by engaging in a different

kind of cognitive gesture. He does not ask a single functional

question. Instead his inquiry is of a metaphysical nature and a

threefold one. He wants to know: "Why is it?" "What is it?" "Who

is it?" ( 1) He wonders: "Why did the world in its totality come into

existence? Why is man confronted by this stupendous and indifferent

order of things and events?'' ( 2) He asks: "What is the purpose

of all this? What is the message that is embedded in organic and

inorganic matter, and what does the great challenge reaching me

from beyond the fringes of the universe as well as froin the depths

of my tormented soul mean?" (3) Adam the second keeps on wondering: "Who is He who trails me steadily, uninvited and unwanted, like an everlasting shadow, and vanishes into the recesses

of transcendence the very instant I turn around to confront this numinous, awesome and mysterious 'He'?

The Biblical dialectic stems from the fact that Adam the first,

majestic man of dominion and success, and Adam the second,

the lonely man of faith, obedience and defeat, are not two different

people locked in an external confrontation as an "I" opposite

a "thou," but one person who is involved in self-confrontation.

"I," Adam the first, confront the "I," Adam the second. In

every one of us abide two personae - the creative majestic Adam the first, and the submissive, humble Adam the second.

 

 

Rejection of either aspect of humanity would be tantamount to an act of disapproval of

the divine scheme of creation which was approved by God as

being very good.

 

 

Finally: woman is created twice with man:Ch 1

 

בְּצֶ֥לֶם אֱלֹהִ֖ים בָּרָ֣א אֹת֑וֹ זָכָ֥ר וּנְקֵבָ֖ה בָּרָ֥א אֹתָֽם׃

And God created humankind in the divine image,
creating it in the image of God—
creating them male and female.

 

Ch 2

Adam is inherently lonely- but only God sees that- Adam is not aware of his loneliness( a key oitn of the Soloveitchik essay)

Adam sees no connection in any of the animals- names them,

וּלְאָדָ֕ם לֹֽא־מָצָ֥א עֵ֖זֶר כְּנֶגְדּֽוֹ׃

but no fitting counterpart for a human being was found.

 

וַיִּקַּ֗ח אַחַת֙ מִצַּלְעֹתָ֔יו וַיִּסְגֹּ֥ר בָּשָׂ֖ר תַּחְתֶּֽנָּה׃ So God יהוה cast a deep sleep upon the Human; and, while he slept, [God] took one of his sides* and closed up the flesh at that site.

וַיִּ֩בֶן֩ יְהֹוָ֨ה אֱלֹהִ֧ים אֶֽת־הַצֵּלָ֛ע ׀

אֲשֶׁר־לָקַ֥ח מִן־הָֽאָדָ֖ם לְאִשָּׁ֑ה וַיְבִאֶ֖הָ אֶל־הָֽאָדָֽם׃ And God יהוה fashioned the side that had been taken from the Human into a woman, bringing her to the Human.

וַיֹּ֘אמֶר֮ הָֽאָדָם֒ זֹ֣את הַפַּ֗עַם עֶ֚צֶם מֵֽעֲצָמַ֔י וּבָשָׂ֖ר מִבְּשָׂרִ֑י לְזֹאת֙ יִקָּרֵ֣א

אִשָּׁ֔ה כִּ֥י מֵאִ֖ישׁ לֻֽקְחָה־זֹּֽאת׃

Then the Human said,
“This one at last
Is bone of my bones
And flesh of my flesh. This one shall be called Woman For from a Human was she taken.”

עַל־כֵּן֙ יַֽעֲזׇב־אִ֔ישׁ אֶת־אָבִ֖יו וְאֶת־אִמּ֑וֹ וְדָבַ֣ק בְּאִשְׁתּ֔וֹ וְהָי֖וּ לְבָשָׂ֥ר אֶחָֽד׃ Hence a man leaves his father and mother and clings to his wife,*wife. so that they become one flesh.

וַיִּֽהְי֤וּ שְׁנֵיהֶם֙ עֲרוּמִּ֔ים הָֽאָדָ֖ם וְאִשְׁתּ֑וֹ וְלֹ֖א יִתְבֹּשָֽׁשׁוּ׃ The two of them were naked,* the Human* and his wife, yet they felt no shame.

Naked- arumim- uncovered-no barrier- no emotional obstacle between them.

 

Of course, it goes downhill from here. The first Adam, as both male and female,  is a managerial personality, who puts aside all emotion, all passion, in the process of building his/her world. The second Adam and Eve have deep love between them, and with it, emotional tensions of expectations, communication, trust. The first Adam and Eve are a theoretical construct- the second pair are real people.

The first may be an ideal—but the Torah is intended for real people.

What is Jewish Standard Time- All about the calendar

 

Jewish Time


Link to presentation: opens at 1:04 into the video of Oct 8

https://youtu.be/hhvPCVmQJiw?t=3882

 

We are all on different time zones.

Yeke Time—10 minutes ahead.

Yemenite time- 15 minutes ahead.

Standard American Jewish- ½ hour late

Standard Israeli time- allow an hour till everyone is organized

Farsi Jewish time- never be the first one to show up at an event.

Chasidic time- when the Rebbe feels like it. Does God wear a watch?

Of course, we are all time obsessed, ever since we put clocks in those beautiful medieval towers.

 

 

Time is a universal topic- Stonehenge- in Britain- a system to mark the seasons.

Mayans, Aztecs- had own calendar systems- 2 systems, one, for agriculture,  ,365 day solar, the other a 260 day cycle for religious events- matched every 52 years.

Romans- The original calendar consisted of ten months beginning in spring with March; winter was left as an unassigned span of days. These months ran for 38 nundinal (nine day) cycles, each forming an eight-day week (nine days counted inclusively, hence the name) ended by religious rituals and a public market. -later, refined by Julius and Augustus Ceasars with 2 extra months, hence July, August. Then,  updated by Pope Gregory, to our current Western calendar.

Islam- pre-Islam, early Arabian calendars merged lunar and solar, but following Mohammed, solely lunar cycle, which is ten days shorter. Basically, then, religious dates move around, compared to the solar. Moslems states have adopted the Gregorian calendar for government and business purposes.

 

How have we measured our years?:

Here is our very first Jewish calendar: Gezer calendar

Gezer, 20 miles west of Jerusalem. It is commonly dated to the 10th century BCE.

The inscription, known as KAI 182, is in Phoenician or paleo-Hebrew script:

 


 

ירחואספ ירחוז

רע ירחולקש

ירחעצדפשת

ירחקצרשערמ

ירחקצרוכל

ירחוזמר

ירחקצ

אבי (ה)

Two months gathering (October, November — in the Hebrew calendar TishreiCheshvan)

Two months planting (December, January — KislevTevet)

Two months late sowing (February, March — ShvatAdar)

One month cutting flax (April — Nisan)

One month reaping barley (May — Iyar)

One month reaping and measuring grain (June — Sivan)

Two months pruning (July, August — TammuzAv)

One month summer fruit (September — Elul)

Abij [ah][9]

 

May have been a school child’s homework assignment-which means children in ancient Israel were being taught literacy! Abi-may be shirt for Abiyah-Yah is my father- oldest form of “ Yah” found. Yarcho- would later be vocalized as “ yarchei”-months of. Yarch- Yareach-month( moon). Connect to” O-reakh”-a visitor- travelling across the night sky.

( Please note- in my video, the source I used for the Gezer inscription had the name” Abij[ah] transcribed in reverse order. I have a better image of the actual tablet, which shows the letters written top to bottom. The student squeezed his name into the available space.)

_____

We know of only 4 months with names:

·        Biblical- marking from Chodesh Haaviv ( of the Springtime) -using lunar sightings-Chodesh- from :Chadash” New- New Moon, Aviv – first month[4]

·        Ziv – second month[5]

·        Ethanim – seventh month[6] and

·        Bul – eighth month.[7]

 

Months , like days, have numbers, not names, as they are not associated with the gods!

Rishon, sheni-. Roman- not Janus, not Mars.

Why no names to days of week- associated with the planets, in turn, each planet , a god- Sun-day, Moon-day,Tuesday ( Ti) Wed(Wotan) Thurs( Thor) Friday-Friga-Sat-Saturn.

Months- Roman- not Janus, not Mars.

 

Why the disconnect? Probably an early concept that God creates time as well as space. Not only is space inside God, but time is also. Time and space are relative. Beat Einstein by a long shot.

 Psalms-

Psalm 90:4 A thousand years in your sight     are like a day that has just gone by,
    or like a watch in the night. י אֶ֪לֶף שָׁנִ֡ים בְּֽעֵינֶ֗יךָ כְּי֣וֹם אֶ֭תְמוֹל כִּ֣י יַֽעֲבֹ֑ר וְאַשְׁמוּרָ֥ה בַלָּֽיְלָה׃

The “ ashmurah”_ night watch-a third of the night ,only!

Also, rejection of the power of heavenly forces that could operate independently. “ Ain Mazal leYisrael”

אִיתְּמַר, רַבִּי חֲנִינָא אוֹמֵר: מַזָּל מַחְכִּים, מַזָּל מַעֲשִׁיר, וְיֵשׁ מַזָּל לְיִשְׂרָאֵל. רַבִּי יוֹחָנָן אָמַר: אֵין מַזָּל לְיִשְׂרָאֵל. וְאַזְדָּא רַבִּי יוֹחָנָן לְטַעְמֵיהּ, דְּאָמַר רַבִּי יוֹחָנָן: מִנַּיִין שֶׁאֵין מַזָּל לְיִשְׂרָאֵל? שֶׁנֶּאֱמַר: ״כֹּה אָמַר ה׳ אֶל דֶּרֶךְ הַגּוֹיִם אַל תִּלְמָדוּ וּמֵאוֹתוֹת הַשָּׁמַיִם אַל תֵּחָתּוּ כִּי יֵחַתּוּ הַגּוֹיִם מֵהֵמָּה״ — הֵם יֵחַתּוּ, וְלֹא יִשְׂרָאֵל.

It was stated that Rabbi Ḥanina says: A constellation makes one wise and a constellation makes one wealthy, and there is a constellation for the Jewish people that influences them. Rabbi Yoḥanan said: There is no constellation for the Jewish people that influences them. The Jewish people are not subject to the influence of astrology. And Rabbi Yoḥanan follows his own reasoning, as Rabbi Yoḥanan said: From where is it derived that there is no constellation for the Jewish people? As it is stated: “Thus said the Lord: Learn not the way of the nations, and be not dismayed at the signs of heaven; for the nations are dismayed at them” (Jeremiah 10:2). The nations will be dismayed by them, but not the Jewish people.Talmud Shabbat 156 a

 

The basis for the calendar is then the month. Very practical- travel at night- use as a guide.The phases of the moon make it easy to track the days that pass. Psychological- it approximates a woman’s period. Rosh Chodesh- a half day festival for women. Depends on witness sightings to identify the first sliver for the New Moon/Month.

However, agriculture requires a different cycle- that of the sun.The festivals are dated from the new moon, the 1st sliver-Rosh Hashanah and Rosh Chodesh, but agricultural- the 15th-mid month, full moon, but it Pesach must be spring harvest, Shavuot must be the conclusion of that harvest time, sukkoth must be the fall harvest- these are solar events. So we have cycles that need to be coordinated. - but also, solar, to match seasons “tekufah.”

                                                                                                                                                                   

 

A moon-month- 28 , divide in half, 14 days, then half again, quarter moon, 7 days, Shabbat. 7 becomes a basic cycle for everything-matches the visible planetary objects-sun-moon-mercury, venus, mars ,Jupiter, Saturn,

It also includes a 7 day cycle, of the week-Shabbat, which is repeated in the two anchor festivals of the year- Pesach and Sukkoth. Seven months apart. Then, a 7 week cycle, Pesach to Shavuot. A 7 year cycle, Shmitah year, a 7 Shmittah cycle, and a separate year- Yovel- Jubilee ( from trumpet blast)-50 years total. Other uses of the 7 cycle-70 years ( Book of Daniel- 70 weeks- as a reference to 70 years- to deliverance.)

Sometime with the return from Babylonian captivity, we accept the Mesopotamian names of months and cycle from Tishrei( tekufat Hashanah), not Nisan( Aviv).same as we now accept Jan, Feb, etc

We now have multiple competing calendars among the children of Israel.

Samaritans- student tour to Shechem- Gerizim, Samaritan synagogue. They were all gathered, fasting- Yom Kippur, by their calculations, about a month after ours.Indeed, their calendar cycle is very similar, but runs one month behind.

Book of Jubilees-an “ external book”-( still preserved by Ethiopian Jews) used a 364 Day Solar Year c 150 BCE.

From Prof Michael Segal-about the book of Jubilees:

 Jubilees follows a solar calendar of 364 days per year, to which it refers as a “complete year” (שנה תמימה):

“Now you command the Israelites to keep the years in this number—364 days. Then the year will be complete and it will not disturb its time from its days or from its festivals because everything will happen in harmony with their testimony. They will neither omit a day nor disturb a festival. (6:32)

A similar calendar has been discovered in some of the Dead Sea scrolls from Qumran. A 364-day calendar is useful from the perspective that the number of days in a year is divisible by 7 (52 weeks = 364 days.13  months of 28 days each). Every date in the calendar is therefore anchored to a specific day of the week, and does not change from year to year.

 

In late Second Temple times (i.e., 1st century BCE to 70 CE), calendrical matters were regulated by the Sanhedrin, or council of elders, at Jerusalem. The testimony of two witnesses who had observed the new moon was ordinarily required to proclaim a new month.

Start counting from Rosh Hashanah- but it is in first of month-what if witnesses come late? Origin of 2 day Rosh Hashanah in Israel. Once, Rosh Hashanah is declared, the other holidays are fine. All of the land of Israel is maybe a fews day hike in any direction. However, how to announce dates of the festivals to Babylonia-hundreds of miles away? Signal flares-Masuot. Set by watchmen on a series of hilltops.

Mishna on Rosh Hashanah-

Initially, they would light torches on the mountaintops, from one peak to another, to signal to the community in Babylonia that the month had been sanctified. After the Samaritans [Kutim] corrupted and ruined this method by lighting torches at the wrong times to confuse the Jews, the Sages instituted that messengers should go out to the Diaspora and inform them of the start of the month.

With that, the communities outside of Israel added one day to each Festival, just in case the messengers would come late.Hence, inUS, 8 days Pesach, 2 day Shavuot, etc, but in Israel one 7, 1, etc.

 

Leap years were proclaimed by a council of three or more rabbis with the approval of the nasi, or patriarch, of the Sanhedrin.

The problem of Pesach- leap year-is added the month before Pesach, Adar. Adar I & Ii. depended at first on witness sightings of signs of spring. What if the witnesses were blocked from appearing? Pesach and Shavuot would be thrown off kilter.

What interference- fight between the eastern and western empires, and the bishop of Rome vs Bishop of Constantinople. 2 different approaches to calculating Easter- based on the start of Pesach. Both churches based themselves on Easter being after Pesach. Eretz Yisrael-under Eastern Empire. If Jewish court could not meet to announce Pesach, the other church could not know when to start Easter!

Jewish persecution under the Roman emperor Constantius II (reigned 337–361) and advances in astronomical science led to the gradual replacement of observation by calculation.

 

Finally, Palestinian patriarch Hillel II introduced a fixed and continuous calendar in 359 CE.

What is the result? This is for the mathematicians:(details from Wikipedia on Hebrew Calendar):

Leap years

The Jewish calendar is based on the Metonic cycle (when the lunar year meets up with the solar year ) of 19 years, of which 12 are common (non-leap) years of 12 months and 7 are leap years of 13 months. To determine whether a Jewish year is a leap year, one must find its position in the 19-year Metonic cycle.

This position is calculated by dividing the Jewish year number by 19 and finding the remainder. (Since there is no year 0, a remainder of 0 indicates that the year is year 19 of the cycle.) For example, the Jewish year 5783 divided by 19 results in a remainder of 7, indicating that it is year 7 of the Metonic cycle.[h]

Years 3, 6, 8, 11, 14, 17, and 19 of the Metonic cycle are leap years.

To assist in remembering this sequence, some people use the mnemonic Hebrew word GUCHADZaT גוחאדז״ט, where the Hebrew letters gimel-vav-het aleph-dalet-zayin-tet are used as Hebrew numerals equivalent to 3, 6, 8, 1, 4, 7, 9. The keviyah records whether the year is leap or common: פ for peshuta (פשוטה), meaning simple and indicating a common year, and מ indicating a leap year (me'uberetמעוברת).[88]

Another memory aid notes that intervals of the major scale   {
\override Score.TimeSignature #'stencil = ##f
\relative c' { 
  \clef treble \time 7/4

} } follow the same pattern as do Jewish leap years, with do corresponding to year 19 (or 0): a whole step in the scale corresponds to two common years between consecutive leap years, and a half step to one common year between two leap years. This connection with the major scale is more plain in the context of 19 equal temperament: counting the tonic as 0, the notes of the major scale in 19 equal temperament are numbers 0 (or 19), 3, 6, 8, 11, 14, 17, the same numbers as the leap years in the Hebrew calendar.

 

A simple rule for determining whether a year is a leap year has been given above. However, there is another rule which not only tells whether the year is leap but also gives the fraction of a month by which the calendar is behind the seasons, useful for agricultural purposes. To determine whether year n of the calendar is a leap year, find the remainder on dividing [(7 × n) + 1] by 19. If the remainder is 6 or less it is a leap year; if it is 7 or more it is not. For example, the remainder on dividing [(7 × 5783) + 1] by 19 is 12, so the year 5783 is not a leap year. The remainder on dividing [(7 × 5784) + 1] by 19 is 0, so the year 5784 is a leap year.[89] This works because as there are seven leap years in nineteen years the difference between the solar and lunar years increases by 7/19-month per year. When the difference goes above 18/19-month this signifies a leap year, and the difference is reduced by one month.

 

The Jewish Talmudic Calendar assumes that a month is uniformly of the length of an average synodic month,(lunar) taken as exactly 291375325920 days (about 29.530594 days, which is less than half a second from the modern scientific estimate); it also assumes that a tropical year is exactly 12719 times that, i.e., about 365.2468 days. Thus it overestimates the length of the tropical year (365.2422 days) by 0.0046 days (about 7 minutes) per year, or about one day in 216 years. This error is less than the Julian years (365.2500 days) make (0.0078 days/year, or one day in 128 years), but much more than what the Gregorian years (365.2425 days/year) make (0.0003 days/year, or one day in 3333 years).

 

In every 19 years, the solar and lunar calendars basically synchronize, with only about 2 hours of difference.

 

Thus each 19 years is called a "small mahzor" in the Jewish Talmudic calendar, which is equivalent to the Greek metonic cycle, although they do not start on the same year. The year of creation according to the Rabbinical Chronology (3761 BCE) is taken as year 1 in the first Small Mahzor. The Greek cycle begins from an arbitrary year, usually from the beginning of the Common Era (Anno Domini).

 

If every 13 Small Mahzor is called an Iggul, because 12 times 2 hours is a day, and 30 days are a month, then in less than 30 Igguls a whole intercalary( ibbur) month should be removed.

The position of the years in a small Mahzor is called the golden number. The pattern of the leap years change slightly in each Iggul, but the Jewish Talmudic calendar fixed the leap years in the year with golden numbers 3, 6, 8, 11, 14, 17, 19. If a Leap year marked L, and the Following year F, and the other common year as O, then

There are other Tweeks in the system: some months 30, some, 29. Which depends on what part of the cycle, because:

 "לא אדו ראש

 (ראש השנה לא יחול בימים א, ד, ו) לא)

 לא בדו פסח" (פסח לא יחול בימים ב, ד, ו) "

1st Day Rosh hashanah cannot fall on Sunday, Weds, or Friday,( and so Yom Kippur will never fall on Friday or Sunday ( can’t  cook a proper meal to eat after the fast on Friday, can’t prepare a good meal for before the fast, and  Hoshanah Rabbah never on Shabbat , because you can’t break the willows, and 1st Day Pesach never on Monday, Weds, Friday, so that it is always the same number of days after Rosh H.

This is only the tip of the iceberg!

Year 5783 since the creation of the world,
according to the traditional count.

·        This year has 355 days,
making it a full (
שלמה) year.

·        In 5783, Rosh Hashanah is on Monday,
while Passover is on Thursday

According to the Machzor Katan, the 19-year (Metonic) cycle used to keep the Hebrew calendar aligned with the solar year:

·        This year is the 7th year of the 305th cycle.
It is not a leap year.

According to the Machzor Gadol, a 28-year solar cycle used to calculate the date to recite Birkat Hachama, a blessing on the sun:

·        This year is the 15th year of the 207th cycle.

According to the current reckoning of sabbatical (shmita) years:

·        This year is the 1st year of the cycle.

·        It is a maaser sheni year.

 

 

 

 

 

 

As a measure of global world events: The seven cycle on a scale of world history:

It is taught in a baraita in accordance with the opinion of Rav Ketina: Just as the Sabbatical Year abrogates debts once in seven years, so too, the world abrogates its typical existence for one thousand years in every seven thousand years, as it is stated: “And the Lord alone shall be exalted on that day

תנא דבי אליהו

 ששת אלפים שנה הוי עלמא שני אלפים תוהו שני אלפים תורה שני אלפים ימות המשיח The school of Eliyahu taught: Six thousand years is the duration of the world. Two thousand of the six thousand years are characterized by chaos; two thousand years are characterized by Torah, from the era of the Patriarchs until the end of the mishnaic period; and two thousand years are the period of the coming of the Messiah.Talmud Sanhedrin 97 a
