The Shast-Sheshi festival (or related to "sixty-six" in Persian) is held annually in the region. Beginning on the sixty-sixth day after Nowruz (the Iranian New Year), the festival corresponds in date and function to the pre-Islamic Zoroastrian feast of Khordadgan, dedicated to the divinity Khordad, the female guardian of water.
