Proclamation of Indonesian Independence ( , or simply '' Proklamasi '' ) was read at 10:00 in the morning of Friday , 17 August 1945 . The wording and declaration of the proclamation had to balance the interests of conflicting internal Indonesian and Japanese interests at the time . The declaration marked the start of the diplomatic and armed resistance of the Indonesian National Revolution , fighting against the forces of the Netherlands and pro-Dutch civilians , until the latter officially acknowledged Indonesia 's independence in 1949 . In 2005 , the Netherlands declared that it had decided to accept de facto 17 August 1945 as Indonesia 's independence date . However , on 14 September 2011 , a Dutch court ruled in the Rawagede massacre case that the Dutch state was responsible because it had the duty to defend its inhabitants , which also indicated that the area was part of the Dutch East Indies , in contradiction of the Indonesian claim of 17 August 1945 as its date of independence . In a 2013 interview the Indonesian historian Sukotjo , among others , asked the Dutch government to formally acknowledge the date of independence as 17 August 1945 . The United Nations recognizes the date of 27 December 1949
