Nowruz Qajari

According to Mary Boyce, "It seems a reasonable surmise that Nowruz, the holiest of them all, with deep doctrinal significance, was founded by Zoroaster himself"; although there is no clear date of origin. Between sunset on the day of the sixth Gahambar and sunrise of Nowruz, Hamaspathmaedaya (later known, in its extended form, as Frawardinegan; and today is known as Farvardigan) was celebrated. This and the Gahambars are the only festivals named in the surviving text of the Avesta.
