Regional/Cultural Day
Araw ng Watawat
The anniversary of the first display of the Philippine flag on May 28, 1898, at the Battle of Alapan in Cavite. The flag was designed by Emilio Aguinaldo and sewn by Marcela Agoncillo, her daughter Lorenza, and Delfina Herbosa de Natividad in Hong Kong. The flag is blue, red, and white, with a yellow sun and three yellow stars. The flag is unique because it can be inverted during wartime: the red stripe on top means the country is at war, and the blue stripe on top means the country is at peace. All government offices and private citizens are encouraged to display the flag from May 28 to June 12.
