National Police Service Day (Araw ng Pambansang Serbisyong Pangpulisya) is observed in the Philippines every August 12. This day commemorates the establishment of the Philippine Constabulary in 1901, which was created to replace the Civil Guard during the American occupation and to maintain peace and order. The Philippine Constabulary later merged with the Integrated National Police to form the Philippine National Police in 1991. The observance serves to honor the men and women serving in the Philippine National Police, recognizing their dedication and service to the community. National Police Service Day is a working holiday, meaning employees do not receive a day off unless it falls on a weekend. This day should not be confused with National Police Anniversary Day, which is celebrated on January 29.
