Jewish Holidays 4395-4400

Warning! Converting between Hebrew and Gregorian dates for very early years is mathematically possible, but the results should be treated as approximations rather than historically precise dates. ^[1]

Dates of major and minor Jewish holidays for years 634-640, as observed in the Diaspora. Each holiday page includes a brief overview of special observances and customs, and any special Torah readings.

Except for minor fasts, holidays begin at sundown on the first date specified and end at nightfall on the last date specified. For example, if the dates for Rosh Hashana are listed as Sep 20-Sep 22, then the holiday begins at sundown on Sep 20 and ends at nightfall on Sep 22.

This page displays the Diaspora holiday schedule. The Israel schedule is used by Jews living in modern Israel.

Rosh Chodesh 🌒

רֹאשׁ חוֹדֶשׁ, transliterated Rosh Chodesh or Rosh Hodesh, is a minor holiday that occurs at the beginning of every month in the Hebrew calendar. It is marked by the birth of a new moon.

Note: the first day of Tishrei is not considered Rosh Chodesh. The holiday that occurs on the 1st day of Tishrei is called Rosh Hashana, the Jewish New Year. For the month of Tishrei, the major holiday of Rosh Hashana takes precedence over what would be a minor holiday.
