I thought that the Biblical commandment was to celebrate the start of the year in spring, at the start of Nisan, but during the Babylonian captivity it was changed to Tishri. The earlier holiday is still known as Rosh Chodeshim (head of the months). I thought RH is more properly known as the Day of Trumpets.
Another little-known Jewish holiday is Yom Machshivim, celebrated in the spring. It commemorates the day when the Jews, wandering in the desert, were commanded to install updates and reboot.
They wouldn’t want to end up with the blue screen of desert.
A “manna”ul update?
