The Commonwealth of the Philippines was inaugurated in 1935. On March 25, 1936, President Manuel L. Quezon issued Executive Order No. 23 which provided for the technical description and specifications of the flag. Among the provisions of the order was the definition of the triangle at the hoist as an equilateral triangle, the definition of the aspect ratio at 1:2, the precise angles of the stars, the geometric and aesthetic design of the sun, and the formal elimination of the mythical face on the sun. The exact shades of colors, however, were not precisely defined. These specifications have remained unchanged and in effect to the present. In 1941, Flag Day was officially moved to June 12, commemorating the date that Philippine independence was proclaimed in 1898.
