How the Jewish calendar works

  • Months follow the moon. Each month is 29 or 30 days and begins with Rosh Chodesh. When the month before has 30 days, Rosh Chodesh is two days: the 30th and the 1st.
  • Years follow the sun. Seven years in every 19 add a second month of Adar, so Pesach always falls in spring.
  • Days begin at sunset. A holiday listed for Wednesday starts on Tuesday evening, and Shabbat and Yom Tov end at nightfall.
  • Outside Israel, the biblical festivals keep a second day of Yom Tov, a custom from when the new month was announced from Jerusalem.
  • Fasts avoid Shabbat. Except Yom Kippur, a fast that falls on Shabbat moves, to Sunday for most and to Thursday for Ta'anit Esther and the Fast of the Firstborn.

Customs for some of these days, especially the Israeli national days and the Omer, vary by community. See also whether Tachanun is said today and Shabbat candle lighting times.

Every one of these days, already in your siddur

SuperSiddur knows the calendar: Hallel, Ya'aleh V'yavo, Al HaNissim, the fast-day readings and Tachanun are already right when you open it, in Ashkenaz, Sfard, Edot HaMizrach, HaGra or Chabad.
