Erev Shavuot

Jewish holidays, also known as Jewish festivals or Yamim Tovim (Hebrew: יָמִים טוֹבִים, romanized: yāmīm ṭōvīm, lit. 'Good Days', or singular Hebrew: יוֹם טוֹב‎ Yom Tov, in transliterated Hebrew [English: ]), are holidays observed by Jews throughout the Hebrew calendar. They include religious, cultural and national elements, derived from four sources: mitzvot ("biblical commandments"), rabbinic mandates, the history of Judaism, and the State of Israel.
