The Tirgon, or Wheat Ripening Festival, dates back to Aryan times. According to the Gregorian calendar, it coincides with the beginning of the calendar month and falls on July 3 of the modern calendar.

The month of Tyre (June 21st to July 21st) falls in the summer. During this month, grains and fruits ripen. The harvest of the hard-working farmers begins. On this day, the people performed rituals, appealing to the spirits of the ancestors, praying that they would save the country from drought.

Tirgon is a festival of wheat ripening, human prosperity, literature and scientists, summer and bright sun.

Celebrating this day is one of the oldest traditions of the ancestors of the Tajik people. According to the available historical data, Tajik scientists and experts have calculated that Tirgon is a harbinger of rains and coincides with the beginning of the calendar month of July.

After scientific research, Tajik scientists found out that almost every two months, when the seasons changed, the ancestors of the Tajiks celebrated a holiday.

Tirgon is on a par with the recently revived in Tajikistan festivals of Sada, a harbinger of the victory of heat over cold, and Mehrgon, a harvest day. This festival is mentioned in the epic poem Shahnameh of Firdaus and other scientific works of the time.
