(in Persian: سپندارمذگان) is the celebration day of love
in ancient Iranian culture. This day is dedicated to Spenta Armaiti
in Middle Persian
, the Middle Iranian language/ethnolect of Southwestern Iran that during Sassanid times (224-654 CE) became a prestige dialect and so came to be spoken in other regions as well.
It is celebrated the 29th of Bahman in Iranian calendar. Modern folklore dates the celebration to ancient times and Zoroastrian tradition.
