Overview

International Day of Nowruz is observed on 21 March. The UN General Assembly recognized the annual day through resolution A/RES/64/253 on 23 February 2010.

Nowruz—whose name means “new day”—is an ancient spring and new-year tradition celebrated across many countries and communities. The UN observance emphasizes cultural diversity, peaceful relations, renewal and shared heritage rather than assigning the tradition to a single modern state.

Why it matters

Nowruz traditions vary across regions, languages and communities. The UN day provides an international framework for appreciating that diversity while encouraging the preservation and transmission of related customs.

UN sources describe Nowruz as associated with the arrival of spring and the vernal equinox. Activities should therefore avoid presenting one household custom, spelling or national form as the only authentic version.

History

In 2009, UNESCO inscribed Nowruz on the Representative List of the Intangible Cultural Heritage of Humanity in a multinational nomination.

Afghanistan, Azerbaijan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, Turkey and Turkmenistan sponsored the revised General Assembly draft. On 23 February 2010, the Assembly adopted A/RES/64/253 without a vote and recognized 21 March as the International Day of Nowruz.

On 21 March 2010, the UN Secretary-General described the occasion as the first International Day of Nowruz.
