The UN's General Assembly in 2010 recognized March 21 as the International Day of Nowruz, describing it a spring festival of Persian origin which has been celebrated for over 3,000 years and calling on world countries to draw on the holiday's rich history to promote peace and goodwill. During the meeting of The Inter-governmental Committee for the Safeguarding of the Intangible Heritage of the United Nations, held between 28 September – 2 October 2009 in Abu Dhabi, Nowrūz was officially registered on the UNESCO List of the Intangible Cultural Heritage of Humanity. In response to the UN recognition, Iran unveiled a postage stamp. The stamp was made public in the presence of Iranian President Mahmoud Ahmadinejad during the first International Nowruz Celebrations in Tehran on Saturday, 27 March 2010. President Ahmadinejad also called for joint efforts to further acquaint the world about the meaningful holiday, adding that it could significantly promote global peace and justice: “Observing Nowruz will not only promote cultural values, but it will also help nations establish relations based on friendship, peace, justice and respect.”
