Actually, it is you who are wrong in assuming I use the "Jews' lunar calendar". I use the Biblical calendar that starts in the month Abib.
The translators correctly used "new moon" in this passage because every new month begins with a new crescent moon as the moon rebuilds until it is full. Consider the following verses that use "yerach".
Exodus 2:2 And the woman conceived, and bare a son: and when she saw him that he [was a] goodly [child], she hid him three months3391.
Deuteronomy 21:13 And she shall put the raiment of her captivity from off her, and shall remain in thine house, and bewail her father and her mother a full month3391: and after that thou shalt go in unto her, and be her husband, and she shall be thy wife.
1 Kings 6:37 In the fourth year was the foundation of the house of YHWH laid,
in the month3391 Zif :
1 Kings 6:38 And in the eleventh year,
in the month3391 Bul, which [is] the eighth month, was the house finished throughout all the parts thereof, and according to all the fashion of it. So was he seven years in building it.
1 Kings 8:2 And all the men of Israel assembled themselves unto king Solomon at the feast
in the month3391 Ethanim, which [is] the seventh month.
2 Kings 15:13 Shallum the son of Jabesh began to reign in the nine and thirtieth year of Uzziah king of Judah; and he reigned a full month3391 in Samaria.
Job 3:6 As [for] that night, let darkness seize upon it; let it not be joined unto the days of the year, let it not come into
the number of the months3391.
Job 7:3 So am I made to possess months3391 of vanity, and wearisome nights are appointed to me.
Job 29:2 Oh that I were as [in] months3391 past, as [in] the days [when] God preserved me;
Job 39:2
Can you number the months3391[that] they fulfil? or know you the time when they bring forth?
Zecariah 11:8 Three shepherds also I cut off
in one month3391; and my soul loathed them, and their soul also abhorred me.
The most important verse above, in my opinion, is 1 Kings 8:2:
And all the men of Israel assembled themselves unto king Solomon at the feast
in the month3391 Ethanim, which [is] the seventh month.
This verse clearly teaches us that the seventh month in Yahweh’s calendar is called “Ethanim”. This is a Hebrew name given to that month prior to the Babylonian captivity. It is also the month in which “the feast” (of Tabernacles) occurs. What is the seventh month called in this verse? “The feast in the
moon Ethanim which is the seventh month”. Why does it call it that? Because Yahweh’s calendar is a lunar-solar calendar in which each new month begins with a crescent moon. The new crescent moon of Ethanim is also Yom Teruah (The Day of Trumpets).
Leviticus 23:24 Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall you have a sabbath, a memorial of blowing of trumpets, an holy convocation.
The word “month” that appears twice in this verse about Yom Teruah is “chodesh”. The “first
day of the chodesh” is the moon Ethanim. This teaches us by extension that every chodesh begins with a moon. A new moon to be precise. That is why all the lexical definitions of chodesh say it can refer to the new moon.
Psalm 104:19 – “He appointed the moon for seasons (moedim): the sun knows his going down.”
The moon is indeed appointed for “moedim” (feasts/appointed times). Without the moon of Ethanim, we would not know when Yom Teruah, Yom Kippur or Sukkot are.
The preservation of a calendar means nothing unless it was preserved in Scripture. I have shown you above how YHWH's calendar, as preserved in Scripture, differs from those other calendars in that the other calendars totally disregard the moon in determining when the feasts fall.
The Bible says nothing about 364 days or 52 weeks. The year is from Abib 1 until the day before the next Abib 1 (between the first new crescent of Abib until the day before the first new crescent moon of the following Abib).
