Rosh Hashanah, meaning "Head of the Year," is the Jewish New Year celebrated in the early autumn. Originally called Yom Teruah in the bible, this holiday is the first of the High Holy Days and commences a ten-day period of repentance culminating in Yom Kippur. Rosh Hashanah also marks the start of a series of autumnal religious festivals, beginning with itself and concluding with Sukkot, followed by Shemini Atzeret in Israel and Simchat Torah elsewhere.
In 1929, Rosh Hashanah was observed on October 5th, representing the latest possible date for the holiday on the Gregorian calendar.
Rosh Hashanah fell on October 5th in 1967, marking the latest Gregorian date for the holiday.
In 2013, the Jewish holiday of Rosh Hashanah fell on September 5th, which is the earliest possible date it can occur on the Gregorian calendar.
In a significant event in 2020, Volodymyr Zelenskyy, the Jewish President of Ukraine, announced that Ukraine would recognize Rosh Hashanah as a national holiday. This decision makes Ukraine the only other country besides Israel to officially observe the Jewish New Year as a national holiday.
Rosh Hashanah is predicted to fall on October 5th in 2043, which will be the latest Gregorian date for the holiday.
Due to the discrepancies between the Hebrew and Gregorian calendars, from 2089 onwards, Rosh Hashanah will no longer fall as early as September 5th.
