As a matter of interest, the Jewish New Year (Biblically, the first day of Israel’s Biblical 7th month, and called the Day of Memorial of Trumpet Blast) is being observed from Sonday (tomorrow) evening and Monday. This is supposed to be observed at the New Moon (the first day of a lunar month).
However, the New Moon began last night (Sept 30), and so the appointed time should have been observed last night and today. More than that, this year the barley was seen in the first Adar month, so there was no need for a second Adar, Biblically-reckoning. So Israel’s 7th month this year — and “Jewish New Year”, or Memorial of Trumpet Blast — should have been a month ago! This, of course, throws off all the other months, and also the actual timing of the Day of Atonements, which is on the 10th of the seventh month, or nine days after the beginning of the lunar month, which is to begin with the New Moon (darkened).

Religious and rationalistic modifications to God’s calendar reckoning have distorted and led astray those who would rely on them for observance and calculations. Praise the Lord for His wisdom that we are not bound to this for our lives as believers in Yeshua, however still significant these appointed times remain for us for other purposes in God’s plan of redemption, and of Israel’s observances during the Millennial Kingdom to come.
