Shavuot( Hebrew: שבועות, lit. "Weeks") is a Jewish holiday that occurs on the sixth day of the Hebrew month of Sivan (late May or early June). Shavuot commemorates the anniversary of the day God gave the Ten Commandments to Moses and the Israelites at Mount Sinai. It is one of the shalosh regalim, the three Biblical pilgrimage festivals. It marks the conclusion of the Counting of the Omer.
The date of Shavuot is directly linked to that of Passover. The Torah mandates the seven-week Counting of the Omer, beginning on the second day of Passover and immediately followed by Shavuot. This counting of days and weeks is understood to express anticipation and desire for the Giving of the Torah. On Passover, the Jewish people were freed from their enslavement to Pharaoh; on Shavuot they were given the Torah and became a nation committed to serving God.Read more.
