Armed Forces Day in Indonesia Date in the current year: October 5, 2024

The history of present-day Indonesian Armed Forces is directly related to Indonesian independence movement. In August 1945, Sukarno proclaimed the independence of Indonesia. However, the Netherlands tried to re-establish their rule over Indonesia. This lead to an armed conflict known as the Indonesian National Revolution.

On October 5, 1945, Sukarno formed the People's Security Army (TKR) in order to defend Indonesia from the Dutch and their allies. This day is considered the birthday of Indonesia's Armed Forces. In 1947, the armed forces gained their current name, Tentara Nasional Indonesia (TNI).

The Indonesian National Armed Forces are voluntary. As of 2014, they comprise approximately 434,000 active personnel. Indonesian military includes the Army, the Navy (including the Marine Corps), and the Air Force.

Indonesian Armed Forces Day is celebrated with impressive military displays held throughout the country, formal receptions and other events. As it is not a public holiday, employees are not granted an extra day off.
