As the winter months come to an end, Mother Nature turns its frost-bitten face towards the spring sun, in hopes of feeling its warmth once again and witnessing the new life blooming everywhere. It is during this time, at the Spring equinox, that Persians all over the world celebrate Nowruz, the Persian New Year. Unlike the Christian New Year that occurs at the exact time every year, Nowruz is calculated according to the days, minutes, and seconds the earth takes to go once around the sun, exactly at the Spring equinox, therefore causing it to be at a different time each year (around March 20 or 21).
