Eid al-Adha is the latter of the two official holidays celebrated within Islam. It honours the willingness of Ibrahim to sacrifice his son Ismael as an act of obedience to God's command. Before Ibrahim could sacrifice his son, however, God provided a lamb to sacrifice instead.
Children's Day is celebrated on 27 May in Nigeria. It was established as a holiday in 1964. It is a public holiday for Primary and Secondary school children. Due to the large size of the country, only a few groups of children (schools or other organizations) are selected to march past in a parade.
Eid ul-Fitr is the earlier of the two official holidays celebrated within Islam. The religious holiday is celebrated by Muslims worldwide because it marks the end of the month-long dawn-to-sunset fasting of Ramadan.
