Shavuot begins at sunset. Called the Feast of the Weeks in the Jewish calendar, this is a time traditionally used to celebrate the harvest season in Israel. Shavuot, which means weeks, always begins exactly seven weeks after Passover. Shavuot is known also as Yom Habikkurim, or "The Day of the First Fruits," because Israel's farmers would bring a bundle from their first harvest to the temple in Jerusalem as a token of thanksgiving to God. Spring harvests in Isreal began with the barley crop at Passover. Each farmer would set aside the first of each type of fruit to ripen, tie it in ribbon, and all would be brought to the city, accompanied by a joyful, musical celebration. The time of Shavuot also commemorates the time when Moses and the Israelites received the Ten Commandments from God at Mount Sinai. Also known as Zeman Matan Toratenu, or the Season of the Giving of Our Law.
