• Spring Equinox, March 20/21st (Farvardin 1st) starts the first day of the Iranian calendar.

According to the Shāhnāma of the poet Ferdousi, King Jamshed (the fourth king of the world – PREHISTORY) was crowned on the first day (Hormazd) of the first month of the parsi calendar which is Farvardin. King Jamshid had command over all the angels and demons of the world and was responsible for a great many inventions that made life more secure for his people: the manufacture of armor and weapons, the weaving and dyeing of clothes of linen, silk and wool, the building of houses of brick, the mining of jewels and precious metals, the making of perfumes and wine, the art of medicine, the navigation of the waters of the world in sailing ships. He was endowed with the royal farr (a radiant splendor that burned about him by divine favor). One day he sat upon a jewel-studded throne and the divs who served him raised his throne up into the air and he flew through the sky. His subjects, all the peoples of the world, marveled and praised him. On this day, which was the first of the month of Farvardin, they first celebrated the holiday of Nawrōz (“new day”). Jamshid was said to have had a magical seven-ringed cup, the Jām-e Jam which was filled with the elixir of immortality and allowed him to observe the universe
