تیر

Named after Tishtrya, the Zoroastrian star deity of rain and water

Tir is named for Tishtrya — the bright star Sirius in Zoroastrian cosmology — who battles the demon of drought and brings the rains. The irony of naming a summer month after rain speaks to Persian wisdom: in the hottest time, you invoke water. The month contains Tirgan, an ancient water festival of joy.
