Shavuot, also known as the Feast of Weeks, is a Jewish holiday celebrated from May 22-23, marking both the wheat harvest in Israel and the biblical event when God gave the Torah to the nation of Israel at Mount Sinai. The holiday concludes the Counting of the Omer, a ritualized counting of 49 days from Passover to Shavuot, symbolizing anticipation for the Torah's revelation. Shavuot is one of the Shalosh Regalim, or Three Pilgrimage Festivals, in Judaism. Customs include adorning homes with flowers and greenery, staying up all night to study in preparation for the Torah's revelation, and attending synagogue services. The Book of Ruth is often read during this time, highlighting themes of acceptance and commitment to the Jewish faith. Shavuot is also associated with the agricultural aspect of the season, celebrating the arrival of spring.
