National Flag Days
Proclamation No. 374 was issued on March 6, 1965 declaring May 28 as National Flag Day to commemorate the date the Philippine flag was unfurled after the Revolutionary Army defeated Spanish forces at the Battle of Alapan, Imus, Cavite in 1898. On May 23, 1994, Executive Order No. 79 was issued extending the period of celebrating National Flag Days from May 28 to June 12.
All Filipinos are encouraged to display the Philippine flag in all offices, agencies and instruments of government, business establishments, schools, and private homes throughout this period. This is to give respect and reverence to our symbol of national sovereignty and solidarity. The Philippine flag is the embodiment of all our country’s ideals, culture, and tradition.
