National Flag Day in the Philippines is celebrated on May 28.

The flag is permanently displayed from May 8 to June 12 (Independence Day) by all government offices and agencies, businesses, educational institutions and private residences. In recent years, the flag days have been extended until June 30 to celebrate the country’s independence and promote patriotism.

Trivia:

The eight rays of the sun featured in the Philippine flag stand for the first eight provinces that stood up against the Spaniards. These provinces are Manila, Cavite, Bulacan, Pampanga, Tarlac, Batangas, Laguna, and Nueva Ecija.
