(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.
