The ancient festival of Tirgan is recognized as a significant element of Iran’s intangible cultural heritage, highlighting enduring connections between nature, mythology, and Iranian society, according to Mohammad-Ebrahim Zarei, head of Iran’s Research Institute of Cultural Heritage and Tourism.

In a statement released over the weekend, Zarei emphasized that Tirgan embodies core values such as hope, prayers for rainfall, social solidarity, and respect for water, which is regarded as a vital source of life in Iranian culture. He described Tirgan as one of the most vibrant expressions within Iran’s cultural calendar, maintaining a dynamic presence in the country’s collective memory over centuries.

Tirgan is traditionally celebrated on the 13th day of the Iranian month of Tir, typically corresponding to July 2 or 3 in the Gregorian calendar. The festival is closely associated with water and rainfall, often marked by water-splashing ceremonies, prayers for rain, and rituals honoring water as a symbol of purity, life, and renewal.

The festival is also linked to Iranian mythology, particularly the legend of Arash the Archer (Arash-e Kamangir). According to the tale, Arash shot an arrow over a great distance to define the borders of ancient Iran. Zarei noted that this story reflects themes of sacrifice, patriotism, and a collective sense of responsibility toward the nation’s destiny, while underscoring the historical relationship between people, their land, and identity.

The Research Institute of Cultural Heritage and Tourism considers festivals like Tirgan essential to safeguarding Iran’s intangible cultural heritage, alongside its rich collection of historical monuments. Efforts to research, document, preserve, and promote these traditions are seen as vital for maintaining Iran’s cultural identity and passing it on to future generations.

Zarei further highlighted that Tirgan serves as a moment to reflect on enduring cultural values such as respect for nature, social responsibility, solidarity, and hope. Along with Nowruz, Yalda Night, and Mehregan, Tirgan remains one of Iran’s oldest and most well-known seasonal festivals.

Today, the observance of Tirgan is primarily maintained by Iranian Zoroastrian communities, although its cultural and historical significance extends beyond religious lines. Historical records of the festival are found in the writings of medieval scholars like Abu Saeid Gardezi, Al-Biruni, and Al-Masudi, as well as in the accounts of European travelers during Iran’s Safavid era.
