Eidul Adha, also known as the Feast of Sacrifice, is a significant religious holiday observed by Muslims globally, and is recognized as one of the two primary Islamic festivals alongside Eid al-Fitr. In the Philippines, particularly amongst the Muslim Filipino communities, Eidul Adha is a special non-working public holiday. The observation coincides with the pilgrimage to Mecca or Hajj, where millions of Muslims participate every year. The festival effectively commemorates the willingness shown by the prophet Ibrahim (also known as Abraham) to sacrifice his son as an act of obedience towards God.

In the Philippines, Eidul Adha is observed with special prayers, feasting, giving of gifts and charity. Prayers usually occur at mosques and prayer grounds, which are followed by the sacrifice of an animal, typically a goat or a sheep, symbolizing Ibrahim's sacrifice. The meat from the sacrifice is divided into three parts -- one for the family, one for relatives and friends, and the last for the poor and needy. This practice emphasizes the Islamic principles of charity and community.

The date of the celebration of Eidul Adha varies annually as it is based on the Islamic lunar calendar. The Philippines' government confirms the date annually based on the declarations made by Saudi Arabia. On this day, families and friends come together to share meals and send each other warm wishes, highlighting the strong community ties and the spirit of sharing embodied by this significant Islamic holiday.
