Counting the Omer

From the day of the Omer offering we are required to count forty-nine days. The day after this counting is complete, the fiftieth day, is the holiday of Shavuot, the anniversary of the giving of the Torah to the Jews. The counting is done out loud at night with a blessing. If one forgot to count by night but remembered by day he should count immediately but he should not make the blessing. If a person missed an entire day he must still count the remaining days but he may not make a blessing.

Because the twenty-four thousand students of Rabbi Akiva (a Sage of the Talmud) died in a thirty-three day period during the time of the counting of the Omer we are required to follow certain practices of mourning for a thirty-three day period during this time. Thus we may not cut our hair, perform weddings, or listen to music during this period. This period of mourning ends on Lag BaOmer, the 33rd day.
