Different astronomical events have been used since Biblical times to establish the Jewish definitions for the hours, days, months, and years. While the Gregorian calendar changes every year (May 25th is on a Monday one year, and a Tuesday the next), Jewish dates are always on the same day.
The Jewish Year is counted from the time of creation, so it is 5783, for the calendar beginning on Rosh Hashanah, which fell on September 26 and 27, 2022, and runs until September 15, 2023. Jewish holidays begin at sunset of the day before the first date shown below.
Another day to mention is the Shabbat, which is the weekly day of rest, lasting 25 hours—from Friday evening, just before sundown, to approximately an hour after sundown on Saturday night—each week.
