Shavuot is observed worldwide on the 6th day of the Hebrew month of Sivan, falling every year seven weeks after Passover. This Jewish holiday, also known as the Feast of Weeks, commemorates the anniversary of the day God gave the Ten Commandments to the Jewish people at Mount Sinai. Traditionally, Jews gather in synagogues to listen to the public reading of the Torah portion that includes the Ten Commandments, and the Book of Ruth is also read during this time. Dairy meals are a customary part of the celebration. Observant Jews often participate in Tikkun Leil Shavuot, an all-night study of Torah, although this practice is not observed by Spanish and Portuguese Jews. In Reform Judaism, confirmation ceremonies for students completing their religious studies are held during this festival. Historically, people were required to bring the first fruits to the Temple in Jerusalem on this day, reflecting its significance as one of the three Biblical pilgrimage festivals.
