Pentecost
You shall count for yourselves -- from the day after the Shabbat, from the day when you bring the Omer of the waving -- seven Shabbats, they shall be complete. Until the day after the seventh sabbath you shall count, fifty days... You shall convoke on this very day -- there shall be a holy convocation for yourselves -- you shall do no laborious work; it is an eternal decree in your dwelling places for your generations. -Leviticus 21:15-16, 21

The period from Passover to Shavu'ot is a time of great anticipation. We count each of the days from the second day of Passover to the day before Shavu'ot, 49 days or 7 full weeks, hence the name of the festival. The counting reminds us of the important connection between Passover and Shavu'ot: Passover freed us physically from bondage, but the giving of the Torah on Shavu'ot redeemed us spiritually from our bondage to idolatry and immorality. Shavu'ot is also known as Pentecost, because it falls on the 50th day.
