Gahambar Paitishem (also spelled Paitishahem) is one of the six seasonal festivals, known as Gahambars, observed in Zoroastrianism, each celebrating a stage of the agricultural year and an aspect of creation. Paitishem marks the bringing in of the harvest, typically falling in mid-September, and is traditionally a time of communal gathering, shared feasting, prayer, and charity, reflecting the Zoroastrian values of generosity and fellowship. Like the other Gahambars, it expresses gratitude to Ahura Mazda for the bounty of creation and emphasizes community, with the food and offerings shared freely among all who attend, regardless of means.
