Shavuot (help·info) (or Shovuos (help·info), in Ashkenazi usage; Shavuʿoth in Classical and Mizrahi Hebrew (Hebrew: שבועות, lit. "Weeks"), known as the Feast of Weeks in English and as Pentecost in Greek, 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 Torah to the entire nation of Israel assembled at Mount Sinai, although the association between the giving of the Torah (Matan Torah) and Shavuot is not explicit in the Biblical text. The holiday 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 people of Israel were freed from their enslavement to Pharaoh; on Shavuot they were given the Torah and became a nation committed to serving God. The word Shavuot means weeks, and the festival of Shavuot marks the completion of the seven-week counting period between Passover and Shavuot. In Hasidic thought, the word Shavuot "Weeks" is interpreted as also an acronym for Shavuot, Bikkurim, Atzeret, Torah. Shavuot is one of the lesser known Jewish holidays among secular Jews in the Jewish diaspora, while those in Israel are more aware of it. According to Jewish law, Shavuot is celebrated in Israel for one day and in the Diaspora (outside of Israel) for two days. Reform Judaism celebrates only one day, even in the Diaspora. Shavuot is unlike other Jewish holidays in that it has no prescribed mitzvot (Torah commandments) other than traditional festival observances of meals and merriment; and the traditional holiday observances of special prayer services and abstention from work. However, it is also characterized by many minhagim (customs). In the 19th century, several Orthodox synagogues in Britain and Australia held confirmation ceremonies for 12-year old girls on Shavuot, a precursor to the modern Bat Mitvah. The early Reform movement made Shavuot into a religious school graduation day. Today, Reform synagogues in North America typically hold confirmation ceremonies on Shavuot for students aged 16 to 18 who are completing their religious studies. The graduating class stands in front of an open ark, recalling the standing of the Israelites at Mount Sinai for the giving of the Torah. Since the Torah does not specify the actual day on which Shavuot falls, differing interpretations of this date have arisen both in traditional and non-traditional Jewish circles. These discussions center around two ways of looking at Shavuot: the day it actually occurs (i.e., the day the Torah was given on Mount Sinai), and the day it occurs in relation to the Counting of the Omer (being the 50th day from the first day of the Counting).
