Philippine Republic Day was originally designated Independence Day celebrating the Treaty of Manila which granted Philippine Independence for the United States on 4 July 1946 in accordance with the terms of the Tydings-McDuffie Act.
It was celebrated as Indendence Day until President Macapagal designated 12 June 1898 as Independence Day marking the date which Emilio Aguinaldo issued the Philippine Declaration of Independence for Spain.
Republic Day was originally a public holiday. President Marcos moved Philippine-American Day to coincide with Republic Day and thereafter referred to the day as Philippine-American Friendship Day, in 1984 it was made a non-working holiday with no mention of Republic Day and formally abolished in 1987 bu President Corazon Aquino.
