The national flag of the Philippines is a horizontal bicolor with equal bands of blue and red, and with a white equilateral triangle based at the hoist side; in the center of the triangle is a golden yellow sun with eight primary rays, each containing three individual rays; and at each corner of the triangle is a five-pointed golden yellow star. The flag is displayed with the blue field on top in times of peace, and with the red field on top in times of war.
The flag was first conceptualized by Emilio Aguinaldo. The first flag was sewn in Hong Kong by Marcela Agoncillo, her daughter Lorenza, and Doña Delfina Herbosa de Natividad, niece of José Rizal, the Philippines' national hero.
According to official sources, the white triangle stands for equality and fraternity; the blue field for peace, truth and justice; and the red field for patriotism and valor. The eight primary rays of the sun represent the first eight provinces (Batangas, Bulacan, Cavite, Laguna, Manila, Nueva Ecija, Pampanga, and Tarlac) that sought independence from Spain and were placed under martial law by the Spaniards at the start of the Philippine Revolution in 1896. The three stars represent the three major geographical divisions of the country: Luzon, the Visayas, and Mindanao.
The flag should be displayed in all government buildings, official residences, public plazas, and schools every day throughout the year. The days from May 28 (National Flag Day) to June 12 (Independence Day) are designated as flag days, during which all government offices, business establishments, and private homes are also encouraged to display the flag.
