Bairam (3 syl.).
The name given to two movable Moslem feasts. The first, which begins on the first day of the moon which follows that of Ramadan, and lasts three days, is a kind of Paschal feast. The second, seventy days later, lasts four days, and is not unlike the Jewish Feast of Tabernacles.
As the Mohammedan year is a lunar one, in 33 years these feasts will have occurred at all the four seasons.
