The proclamation is based on Republic Act 9849, which provides that Eid’l Adha, although a movable feast, shall be observed as a national holiday.
Aquino’s Proclamation No. 60 stated that the National Commission on Muslim Filipinos has confirmed that the feast of Eid’l Adha shall fall on November 16.
Eid’l Adha is one of Islam’s two major festivals celebrated by 1.6 billion Muslims around the world.
