The holiday was created by Republic Act No. 9256, which was signed into law by President
Gloria Macapagal Arroyo on February 25, 2004, twenty-one years after his death and eighteen years after the People Power Revolution, and was sponsored by
Senate President Franklin Drilon and
House Speaker Jose de Venecia Jr. It requires an EDSA People Power Commission (EPPC) to hold activities in observance the day and shall be funded from the Budget of the
Office of the President and from private donations. This holiday was created for the late Senator
Ninoy Aquino while simultaneously declaring via proclamation
Jose W. Diokno Day on February 27 for the other martial law hero. Both Aquino and Diokno were the first senators imprisoned under martial law. A commemoration ceremony was held at the
People Power Monument in
Quezon City, which was attended by Presidents Arroyo and Aquino with her family, and government officials such as members of the cabinet, top police, and military brass. The holiday was included in President Arroyo's program of "holiday economics", adjusting the observance of the holiday to the nearest Monday in order to boost the tourism industry with long weekends. In 2010, it was moved back to its original date by Aquino's son, President
Benigno Aquino III. In 2022, during the first Ninoy Aquino Day under President
Bongbong Marcos, the son of the late President
Ferdinand Marcos, most official government agencies' social media accounts were noticeably silent. There was also no commemorative statement from the
Office of the President for that year, but began releasing such from 2023 onwards. In 2024, the observance was moved to Friday, August 23, through Proclamation No. 665, signed by President Bongbong Marcos on August 15. The adjustment was made to create a longer weekend that would encourage domestic tourism, as Monday, August 26, is already declared as
National Heroes Day. However, Representative
Edcel Lagman (
Albay–1st) and
Bagong Alyansang Makabayan's Renato Reyes separately criticized the move, with Lagman calling it illegal, citing Republic Act No. 9492, which requires that holidays on a Wednesday be moved to the preceding Monday with six-month prior notice. ==Ceremonies==
