Shavuot (or Shavuos, in Ashkenazi usage; 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). It marks the conclusion of the Counting of the Omer and the day the Torah was given to the Jewish people at Mount Sinai. It is one of the shalosh regalim, the three Biblical pilgrimage festivals.

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 accepted the Torah and became a nation committed to serving God.

In the Bible, Shavuot is called the Festival of Weeks (Hebrew: חג השבועות, Hag ha-Shavuot, Exodus 34:22, Deuteronomy 16:10); Festival of Reaping (Hebrew: חג הקציר, Hag ha-Katsir, Exodus 23:16), and Day of the First Fruits (Hebrew יום הבכורים, Yom ha-Bikkurim, Numbers 28:26). The Mishnah and Talmud refer to Shavuot as Atzeret (Hebrew: עצרת, a solemn assembly), as it provides closure for the festival activities during and following the holiday of Passover. Since Shavuot occurs 50 days after Passover, Christians gave it the name Pentecost (πεντηκόστη, "fiftieth day"). As this always falls on a Sunday, "Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the Lord." Leviticus 23:16. Sunday is the First Day of the week, the "morrow" after the "sabbath".

In Israel and for Reform Jews, Shavuot is celebrated for one day. Outside Israel, the holiday is mostly celebrated for two days.
