Answer: Eid al-Fitr, also called the "Festival of Breaking the Fast", is a religious holiday celebrated by Muslims worldwide that marks the end of the month-long dawn-to-sunset fasting of Ramadan. This religious Eid is the first and only day in the month of Shawwal during which Muslims are not permitted to fast.
Eid al-Adha also called the "Festival of the Sacrifice", is the second of two Islamic holidays celebrated worldwide each year, and considered the holier of the two. It honours the willingness of Ibrahim to sacrifice his son as an act of obedience to God's command.
