National Flag Day in the Philippines is observed every May 28, commemorating the first use of the Philippine flag following the victory in the Battle of Alapan in 1898. The flag, created by Filipino revolutionary Emilio Aguinaldo in 1897, features a horizontal bicolor of royal blue over scarlet red, with a white equilateral triangle at the hoist, a golden sun with eight rays in the center, and a five-pointed gold star at each vertex. The flag was first raised after the Filipino revolutionaries, led by Aguinaldo, defeated Spanish troops and recaptured Cavite. During this observance, the national flag is prominently displayed from May 28 to June 12, which is Independence Day, by government offices, businesses, educational institutions, and private residences. In recent years, the flag display period has been extended until June 30 to further celebrate the country's independence and promote patriotism.
