Nowruz, also known as Persian New Year, is a celebration that marks the beginning of spring and the first day of the Persian calendar. It is a time of joy, renewal, and new beginnings for millions of people around the world, particularly in countries like Iran, Afghanistan, Tajikistan, and parts of Central Asia. The word Nowruz means "new day" and the holiday is typically celebrated on the vernal equinox, which falls on March 21st. However, the festivities usually last for several days, with preparations beginning weeks in advance.
