Shavuot, or Shavuos inAshkenazic usage, is aholiday celebrated byJewish people. They celebrate it to remember the dayGod gave theTorah to the entire nation ofIsrael assembled atMount Sinai. The holiday association between the giving of the Torah (Matan Torah) and Shavuot is notexplicit in the Biblical text.
Shavuot is celebrated on the sixth day of the Hebrew month ofSivan, which may occur in May or June. It falls 49 days afterPassover(Pesach), which comes before Shavuot. It marks the end of the Counting of the Omer (Sefirat HaOmer).Pentecost falls around the time of Shavuot.
InSecularJews of theDiaspora, Shavuot is one of the Jewish holidays known to not be celebrated as much, while the people in Israel celebrate it every year.[1][2]
Shavuot is celebrated by all types of Orthodox Jewry, ranging from Modern to ultra-Orthodox. It is one of the three pilgrimage holidays celebrated by Jews. (The other two being Passover, and Sukkot, or 'Festival of the Tabernacle'.)
According toJewish law, Shavuot is celebrated inIsrael for one day and in the Diaspora (outside of Israel) for two days.Reform Jews celebrate only one day.[3]
