Mazandaran Tirgan Festival in Amol/Sari region
Tirgan falls on Tir 13 in early July, a midsummer Zoroastrian festival honoring the legendary archer Arash rather than any spring Nowruz tradition, with Mazandaran communities near Amol and the Larijan foothills tossing colored ribbons into rivers as wishes for rain, alongside dancing, poetry, and shared seasonal meals.
Tirgan falls on the thirteenth day of the Zoroastrian month of Tir, a fixed point in the ancient Iranian calendar that lands in early July and has no connection to the spring equinox celebrations of Nowruz two full seasons earlier.
