Often celebrated outdoors in a large space or inside a big hall or mosque Muslims will pray and later prepare a special feast to give thanks and praise to God. Eid al-Fitr is not a federal national holiday but rather an observance to mark the end of the month of Ramadan and celebrate with a feast to praise god.
The tradition of Eid al-Fitr was originated out of festivals in Madinah after the migration of the prophet Muhammad from Mecca. This day has many different names including Feast of Breaking the Fast, Sugar Feast, Bayram and the Sweet Festival.
