About Republic Day (Philippines; July 4 historical statutory commemoration)

Philippine Republic Day is a July 4 historical statutory commemoration created by Republic Act No. 4166 in 1964.

The same law moved Philippine Independence Day from July 4 to June 12 and named July 4 Philippine Republic Day.

Why Republic Day (Philippines; July 4 historical statutory commemoration) matters

July 4 retained a commemorative role after the statutory Independence Day date moved to June 12.

Current nationwide regular-holiday law does not list July 4, so historical Republic Day status should not be presented as a current nationwide regular holiday.

History of Republic Day (Philippines; July 4 historical statutory commemoration)

Before Republic Act No. 4166, Philippine Independence Day was observed on July 4.

Republic Act No. 4166, approved August 4, 1964, changed Independence Day to June 12 and declared July 4 Philippine Republic Day; it also listed July 4 among legal holidays at that time.

Republic Act No. 9492, approved July 25, 2007, set out a later national list of regular holidays and nationwide special days that does not include July 4.

A current Department of the Interior and Local Government advocacy calendar still lists July 4 as Republic Day with references to Republic Act No. 4166 and Proclamation No. 811, illustrating commemorative use distinct from current nationwide regular-holiday status.
