Philippine Declaration of Independence
Following the end of World War II, the United States granted independence to the Philippines on 4 July 1946 via the Treaty of Manila. July 4 was observed in the Philippines as "Independence Day" until August 4, 1964 when, upon the advice of historians and the urging of nationalists, President Diosdado Macapagal signed into law Republic Act No. 4166 designating June 12 as the country's "Independence Day". June 12 had previously been observed as "Flag Day" and many government buildings are urged to display the Philippine Flag in their offices.
Independence Day (Philippines)
The United States of America granted independence to the Philippines on July 4, 1946 through the Treaty of Manila. July 4 was chosen as the date by the United States because it corresponds to the United States' Independence Day, and that day was observed in the Philippines as "Independence Day" until 1962. On May 12, 1962, President Diosdado Macapagal issued Presidential Proclamation No. 28, which declared June 12 a special public holiday throughout the Philippines, "... in commemoration of our people's declaration of their inherent and inalienable right to freedom and independence." On August 4, 1964, Republic Act No. 4166 renamed July 4 holiday as "Philippine Republic Day", proclaimed June 12 as "Philippine Independence Day", and enjoined all citizens of the Philippines to observe the latter with befitting rites.
