United Nations observances contribute to the achievement of the purposes of the UN Charter and promote awareness of and action on important political, social, cultural, humanitarian or human rights issues. They provide a useful means for the promotion of international and national action and stimulate interest in United Nations activities and programmes. For international years and decades the UN Secretary General takes action to establish the preparatory process, evaluation and follow-up procedures.

The majority of observances have been established by the UN General Assembly and some have been designated by UN specialized agencies.

In 1950, the General Assembly approved the first international day — Human Rights Day — to be observed on 10 December. Resolution 423 (V) invited all states and international organizations to observe this day to celebrate the proclamation of the Universal Declaration of Human Rights by the General Assembly on 10 December 1948, and to exert increasing efforts in this field.

Every year numerous days are celebrated not just to remind people of diseases but to also to unite people of our mother earth. These days are celebrated with a unique zeal and zest all over the world in accordance with the culture and norms of a particular geographical area. But the basic and fundamental aim of celebration of these days is to unite people, peace across the world.
