Nowruz Day which is the Iranian New Year, also familiar as the Persian New Year, marks the beginning of the spring equinox, as well as the first day of Farvardin, the first month of the Iranian solar calendar. 
Nowruz is celebrated worldwide by various ethno-linguistic groups, and falls on or around March 21 of the Gregorian calendar.
This year in Iran, COVID-19 pandemic curbs dampened the traditional spirit associated with the annual celebrations amid a spike in new cases in several cities.
Moreover, people also launch firecrackers, go on family outings and take a lengthy break from work.
