In the vast but arid and semi-desert land of Iran, rain has always been life-giving and effective for the people. Due to this, the goddess of rain “Tištar Yašt” has been left from the ancient times of Iran, Which is highly respected and praised. And the celebration of Tῑrgān, which is held in this period, is a reminder of the importance of the rain god in ancient times. In an ancient village called Sharifābād, which dates back to the eighth century AH. Many Mobeds who lived in this village in the past have played an effective role in guiding the Zoroastrians and Parsees in India. An ancient celebration was held in honor of the Tištrya named Tištarīm with a special ritual. This special ritual of holding Tištarīm has not been reported anywhere else. However, in this village, a festival called Tīr-Māhi is also held, which is similar to the Tῑrgān festival in other places. By collecting field documents related to the two celebrations of Tištarīm and Tīr-Māhi in this village, apart from getting acquainted with these and the way they are held, we seek the answer to this question. Did the people of this village differentiate between these two celebrations “Tištarīm and Tīr-Māhi”? And did they recognize both of them? Considering that these people never mention them alone in the mention of the two gods, Tir and Tishtar, and always refer to them together as "Tir and Tishtar", and during one year, at two different times to celebrate the ritual and that according to the available evidence of active priests and awareness lived in this village, it is believed that these people in the distant past, between the gods of Tir and Tishtar. most of this is the goddess of rain, who has etiquette because of the goddess and the dry land of Yazd, but it should be remembered that in The common chronology there is this Tir that between the days of the month and between the months of the year and arises from the equalization and accompaniment of the name of the day and the month is Tirgan.
