In 1977, the General Assembly called for the annual observance of 29 November as the International Day of Solidarity with the Palestinian People (resolution 32/40 B).
On that day, in 1947, the Assembly adopted the resolution on the partition of Palestine (resolution 181 (II)) In resolution 60/37 of 1 December 2005, the Assembly requested the Committee on the Exercise of the Inalienable Rights of the Palestinian People and the Division for Palestinian Rights, as part of the observance of the International Day of Solidarity with the Palestinian People on 29 November, to continue to organize an annual exhibit on Palestinian rights or a cultural event in cooperation with the Permanent Observer Mission of Palestine to the UN.
The observance of the International Day of Solidarity with the Palestinian People also encouraged Member States to continue to give the widest support and publicity to the observance of the Day of Solidarity. In 2015, the Palestinian flag was raised at the Headquarters and Offices of the United Nations.
The UN General Assembly adopted the resolution on raising the flags of non-member observer States at the United Nations (A/RES/69/320).
The United Nations decided that the flags of non-member observer States, including the flag of the State of Palestine, shall be raised at Headquarters and United Nations offices following the flags of the Members States of the Organization.
The Ceremony of the Raising of the Flag of the State of Palestine at the UN headquarter in New York took place on September 30th 2015.
