๐Ÿ‡ต๐Ÿ‡ญ Philippines Flag Day – 28th May

Araw ng Watawat — celebrating the first unfurling of the Philippine flag

28th May Philippines Flag Day Araw ng Watawat Battle of Alapan Philippine flag Emilio Aguinaldo


Every year from 28th May to 12th June (Independence Day), the Philippines celebrates Flag Day (Araw ng Watawat) — a period of national flag consciousness. The main observance on May 28 commemorates the first unfurling of the Philippine flag after the Battle of Alapan on May 28, 1898, during the Philippine Revolution against Spanish colonial rule.

Flag Day marks the victory of Filipino revolutionary forces led by General Emilio Aguinaldo over Spanish troops in Imus, Cavite. The flag was first flown in that battle, then formally unfurled on June 12, 1898 (Independence Day). Since 1994, by presidential proclamation, the entire period from May 28 to June 12 is dedicated to the flag, with May 28 as the primary Flag Day.
