World Day

International days are used to address essential aspects of human life, important issues of the world or history and to raise public awareness. The following is a list of important international days or World Day.

UN calendar international day

An international day (or world day) is a day of the year dedicated to a particular theme at an international or global level. The UN calendar provides more than 140 world (or international) days. The first, instituted in 1950 — World Human Rights Day — was established on December 10. Exactly two years earlier, on December 10, 1948, the General Assembly of the United Nations adopted the Universal Declaration of Human Rights.

The themes of international days are always associated with the main areas of action of the United Nations, namely the maintenance of international peace and security, promotion of sustainable development, protection of rights, guarantees of international law, etc.
