Nowruz Qajari

As the spring equinox, Nowruz marks the beginning of spring in the Northern Hemisphere. The moment the Sun crosses the celestial equator and equalizes night and day is calculated exactly every year, and families gather together to observe the rituals. While Nowruz has been celebrated since the reform of the Iranian calendar in the 11th century CE to mark the new year, the United Nations officially recognized the "International Day of Nowruz" with the adoption of UN resolution 64/253 in 2010
