United Nations Day, which is celebrated annually on October 24, was proclaimed in October 1947 by a resolution of the UN General Assembly (No. 168) and is timed to coincide with the anniversary of the entry into force in 1945 of the UN Charter.
In 1971, the General Assembly, in its resolution (No. 2782), emphasizing that United Nations Day should become an international holiday, recommended that Member States observe it as a public holiday.
The UN is an international organization of states created to maintain and strengthen international peace, security, and development of cooperation between countries.
