Significance

Jashn-e Tiri is a summer festival honoring the day when the name of the month (Tir) and the name of the day (Tir) coincide — doubling the sacred power of Tishtrya, the yazad of the star Sirius who brings the rains. The Tishtar Yasht (Yasht 8) describes Tishtrya's cosmic battle against the demon of drought Apaosha: Tishtrya takes the form of a white horse and gallops across the sky, finally defeating the black horse of drought and releasing the rains. This is a day of joy, water, and gratitude for the life-giving power of summer storms.
