Babylon had the same calendar as Israel because that was the ONLY calendar on earth at that time.  Israel adopted
the names for the months while in Babylon and their crescent moon/new moon, but their calendars were nearly
identical otherwise.  In fact, Emmanuel Velikovsky discovered that if you go back in time, at one point you will
discover that all nations had the same calendar, regardless of where they lived on the planet.  All nations had twelve
30 day months for a 360 lunar-solar calendar year.

Israel had Torah.  Babylon had the tradition of their fathers, and these same "fathers" were related to the patriarchs
Noah and his sons.  Babylon served her false deities using the SAME calendar that Israel used to worship Yah.  I
believe that is why Yah confused the languages at the tower of Babel (they were using the language of Eden to
build the tower), and why Yah eventually dented His clock, knowing that Israel alone would continue to keep the
Calendar of Creation while all others would settle on a calendar of their own choosing.

The Jews (Khazars) adopted the calendar and religion of the Babylonian Israelite rabbis (offspring of those who did
not return to Israel with Ezra and Nehemiah).  The Jews (who are NOT Israelites) never kept a lunar Sabbath, and
they copied the amalgamated religion of the Babylonian rabbis.  So no, the lunar Sabbath did not come from
Babylon, it came from YHVH, but was altered by the wicked men throughout history.

“The Babylonian calendar was a lunisolar calendar with years consisting of 12 lunar months, each beginning when a
new crescent moon was first sighted low on the western horizon at sunset, plus an intercalary month inserted as
needed by decree. The calendar is based on a Sumerian (Ur III) predecessor preserved in the Umma calendar of
Shulgi (ca. 21st century BC).”

“The beginning of the month in the Babylonian calendar was determined by the direct observation by priests of the
young crescent moon at sunset after the astronomical New Moon.”

The link, http://www.tyndale.cam.ac.uk/Egypt/ptolemies/chron/babylonian/chron_bab_cal.htm, leads you to
this quote:  “The Babylonian calendar was a lunisolar calendar. The Babylonian day began at sunset, and each
month notionally began with the first rising of the crescent moon; in essence, a Babylonian month was a synodic
lunar month, represented as a 29 or 30 day month. Contemporary records show that the start of the month was
actually determined by observation of the new moon wherever possible, or by prediction if not.’”

“The months began at the first visibility of the New Moon, and in the 8th century BC court astronomers still reported
this important observation to the Assyrian kings.
“Thus, the Babylonian calendar until the end preserved a vestige of the original bipartition of the natural year into
two seasons, just as the Babylonian months to the end remained truly lunar and began when the New Moon was first
visible in the evening. The day began at sunset. …. The Jewish adoption of Babylonian calendar customs dates
from the period of the Babylonian Exile in the 6th century BC.”

Note
:  You might be tempted to say, SEE!  But you’d be wrong.  These websites accurately record the events as
history reveals them.  It was the "Jews" who adopted the Babylonian calendar, including the days beginning at
sunset (the days in Scripture begin at dawn), the months beginning with the first visible crescent, as well as the
pagan names of the months and having eggs on the table at Passover (along with other pagan traditions).  The
Jews are not Israelites; they are Khazars (Edomites).  All the months in Scripture are by ordinal numbers.  The
Israelites certainly apostatized and fell into the same or similar calendar corruption as the Jews, but there the
similarities cease.

In the article
Shawui Calendar: Ancient Shawui Observance, we find confirmation of a radical change in YHVH’s
calendar.  “The [lunar]...calendar was used by all the original disciples of Yeshua...  This original Nazarene lunar-
solar calendar was supplanted by a Roman ‘planetary week’ and calendar in 135 C.E. -- when the ‘Bishops of the
Circumcision’ (i.e. legitimate Nazarene successors to Yeshua) were displaced from Jerusalem.  This began a three
hundred year controversy concerning the true calendar and correct Sabbath.”

“This intimate connection between the week and the month was soon dissolved.  It is certain that the week soon
followed a development of its own, and it became the custom -- without paying any regard to the days of the month (i.
e. the lunar month) -- ...so that the New Moon no longer coincided with the first day [of the month ].”  
Encyclopedia
Biblica, (1899 edit.), p. 5290.

“… the custom of celebrating the Sabbath every 7th day, irrespective of the relationship of the day to the moon’s
phases, led to a complete separation from the ancient view of the Sabbath...”  
Encyclopedia Biblica, (1899 edit.),
p. 4179.   

“The calendar was originally fixed by observation, and ultimately by calculation.  Up to the fall of the Temple (A.D.
70), witnesses who saw the new moon came forward and were strictly examined and if their evidence was accepted
the month was fixed by the priests.  Eventually the authority passed to the Sanhedrin and ultimately to the
Patriarch.  …  Gradually observation gave place to calculation.  The right to determine the calendar was reserved to
the Patriarchate; the Jews of Mesopotamia
[Ed.—this is the land of Babylon] tried in vain to establish their own
calendar but the prerogative of Palestine was zealously defended.  So long as Palestine remained a religious
centre, it was naturally to the homeland that the Diaspora looked for its calendar.  Uniformity was essential, for if
different parts had celebrated feasts on different days confusion would have ensued.  It was not until the 4th century
A.D. that Babylon fixed the calendar…”  
Encyclopedia Britannica: Vol. 4, article “Calendar”.

“These imported [from Babylon] superstitions eventually led Jewish rabbis to call Saturn Shabbti, ‘the star of the
Sabbath,’ [and]...it was not until the first century of our era, when the planetary week had become an established
institution, that the Jewish Sabbath seems always to have corresponded to Saturn’s Day [Satyrday].”  
Hutton
Webster
in his book, Rest Days, p. 244.  Thus the condemnation in Amos 5:26 was set in stone.

In Amos 5:26, the prophet is recorded as reminding Israel of their apostasy.  Israel started worshipping Chiun, a star-
god of their own making.  In Acts 7:43, Stephen quotes Amos and is translated into Greek as saying “Remphan, the
star-god…”  Chiun and Remphan are the respective Hebrew and Greek words for Saturn.  The Sabbath of Scripture
is based upon the lunar cycle.  So Israel did indeed come to worship Saturn on his day, but at a much later date and
not by Divine command.  

“With the development of the importance of the Sabbath as a day of consecration and the emphasis laid upon the
significant number seven, the week became more and more divorced from its lunar connection...”

Encyclopedia: Vol. 10, 1943 edit. Article, "Week," p. 482.
17.  The Luni-solar calendar is Babylonian in origin.
