Tir-Rooz festival on the 13th day (Tir day) of Mehr month, honoring Tishtar, the deity of rain. This festival reminds us of Tishtar's importance throughout the year, not just in Tir month.
Origin
Zoroastrian; Tir day in Mehr month
Historical Context
In Zoroastrianism, when the day name matches the month name, that day is celebrated. However, named days in other months also hold importance. Tir day in Mehr month is an opportunity to remember Tishtar's role in bringing rain and fertility to the earth.
Fun Facts
In the Zoroastrian calendar, each day has a name, and the 13th day is called Tir. Tishtar is the deity of rain, praised in the Tir Yasht and identified with the star Sirius. The battle between Tishtar and Apaosha (demon of drought) is one of the most important Zoroastrian myths.
