Jewish holiday

Jewish holidays, also known as Jewish festivals or Yamim Tovim (ימים טובים, "Good Days", or singular יום טוב Yom Tov, in transliterated Hebrew [English /ˈjɔːm ˈtɔːv, joʊm ˈtoʊv/]), are holidays observed in Judaism and by Jews throughout the Hebrew calendar and include religious, cultural and national elements, derived from three sources: Biblical mitzvot ("commandments"); rabbinic mandates; Jewish history and the history of the State of Israel.

Certain terms are used very commonly for groups of holidays.

Certain terminology is used in referring to different categories of holidays, depending on their source and their nature:

Shabbat (שבת) (Ashkenazi pron. from Yiddish shabbos), or Sabbath, is referred to by that name exclusively. Similarly, Rosh Chodesh (ראש חודש) is referred to by that name exclusively.
