The Presidential Communications Operations Office (PCOO) has declared that Monday, May 25, will be a regular holiday.
President Rodrigo Duterte signed Proclamation No. 944, marking the observance of Eid'l Fitr (the Feast of Ramadan).
The report notes:
Due to RA 9177 (established in November of 2002), the Philippines celebrates the Muslim holiday nationwide. However, the date is not fixed since the Muslim calendar is based on the different phases of the moon.
