Sundown today begins the Shavuot, or the Feast of Weeks, in the Hebrew religion. Its counterpart in Christianity is Pentecost, which we celebrate tomorrow beginning in the morning. In Judaism, Shavuot is a celebration of both the wheat harvest and the giving of Torah. In Christianity, Pentecost is the day of the Holy Spirit's descent on the church. The word "pentecost" is Greek for 50th, because Shavuot occurs a week of weeks (7x7 days) after Passover. Thus, for us, it is the 50th (and final) day of Easter.
