Eidul Adha is a Muslim celebration that honors the willingness of Ibrahim (Abraham in Jewish and Christian Traditions) to obey Allah and also commemorates the end of the hajj (pilgrimage to Mecca). In the Islamic calendar, Eidul Adha is celebrated on the tenth day of Zhul Hijja (12th and final month). As the Islamic calendar is a lunar calendar, the date to celebrate Eidul Adha constantly changes. In the Philippines, President Duterte has signed proclamation no. 789 to confirm the holiday to be observed throughout the country.
