An official UN holiday celebrated by people around the world
Nowruz is a holiday celebrated annually on March 21 internationally. It’s the first full day after the “vernal equinox, [and] is celebrated as the beginning of the new year by more than 300 million people all around the world”. As the first official day of spring it’s a holiday that goes back over 3,000 years in the Balkans, the Black Sea Basin, the Caucasus, Central Asia, and the Middle East, now spreading to Europe and North America. In 2010 the UN declared March 21 International Day of Nowruz.
