Bairam, the Persian and Turkish name for a Mohammedan festival somewhat analogous to our Easter, immediately following the fast of Ramadan and lasting three days. Seventy days afterwards the Second Bairam is celebrated, in commemoration of the sacrifice of Isaac. The Mohammedan year being lunar (354 clays), the festivals run through all the seasons in 33 years.
