Remarks

For calculating Eid al-Fitr and Eid al-Adha, there are two main approaches (calendars) used in practice, and they sometimes overlap. Umm al-Qura calendar is used by Saudi Arabia (primary user) and some Gulf countries. Moon sighting calendar is used by South Asia, Central Asia, Middle East and North Africa.
