About Ninoy Aquino Day

Ninoy Aquino Day is observed in the Philippines on August 21 to remember former senator Benigno S. Aquino Jr., who was killed on August 21, 1983. Republic Act No. 9256 declares the anniversary a special nonworking holiday.

The legal category is important: a special nonworking holiday is not identical to a regular Philippine holiday and has different applicable labor rules. Annual proclamations may affect scheduling; consult the target year’s official calendar.

Why Ninoy Aquino Day matters

The day is associated with remembrance, Philippine democratic history and reflection on civic institutions. People may engage with the historical record from differing political perspectives while treating victims and families with respect.

Public activities can include museum learning, historically grounded discussion and remembrance. Statements about disputed political responsibility must distinguish documented acts from interpretations.

History of Ninoy Aquino Day

Aquino was assassinated at Manila International Airport on August 21, 1983, following his return to the Philippines. Republic Act No. 9256, approved on February 25, 2004, established an annual August 21 special nonworking holiday in his memory.

The Philippine government’s 2026 holiday proclamation and Department of Labor guidance list Friday, August 21, 2026 as a special nonworking day. A one-year public notice does not erase the underlying statutory anniversary or automatically define dates for every subsequent year.
