Let’s briefly look at the Feast of Trumpets (Yom Teruah) vs. Rosh Hashanah (head of the year).
This month [Abib] shall be the beginning of months for you; it is to be the first month of the year for you. Exodus 12:2
The first day of the year, according to scripture, is the first day of the first month, which was called “Abib,” but after the Babylonian captivity, it was called “Nisan,” because the physical Jews adopted month names that were tied to Babylonian paganism. The first month occurs on the new moon that follows the barley being declared “abib,” which means “young ears.” It signals the beginning of the annual barley harvest.
Babylonian paganism also influenced the Jews in their calling the first day of Tishrei (the seventh month) the “new year.” So, the Feast of Trumpets (Yom Teruah) became considered the beginning of the civic new year. But, just like so many false pagan teachings in christianity, those same influences had also crept into the thinking of the physical Jews, and the idea of “Rosh Hashanah” being on the Feast of Trumpets is just as pagan as christ-mass and hanukkah are.
The month of Nisan is the first month of the year, and 14 Nisan is Passover, which begins the Spring feasts. Celebrating the “new year” on the Feast of Trumpets is just as false as celebrating Messiah’s birth on Dec. 25, or hanukkah at all. They are all false traditions of men, as christ-mass and hanukkah are just counterfeits of the Feast of Tabernacles (Sukkot).
The traditions of men are devoid of the Holy Spirit, as He dwells only in truth, and thus, He is not in the traditions of men that are contrary to the Father’s traditions.
The Feast of Trumpets is NOT the first day of the new year. It is the first day of the seventh month of the year. The new year (Rosh Hashanah) is the first day of the first month (Abib/Nisan).
So, “SHANA TOVA” is a false greeting in the Fall. It ONLY applies to the first day of the first month, which is in the Spring.
