As of 6th December, 2023, the United Nations cultural agency, UNESCO, has listed the Sadeh celebrations as a global form of intangible heritage, based on a case submitted by Iran and Tajikistan. Dating back to the Achaemenid Empire, Sadeh is a mid-winter festival celebrated by the Zoroastrian community in Iran and other countries, meant to defeat the forces of darkness and cold.

The inscriptions were granted during UNESCO’s 18th session of the Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage, which were held on from 4^th – 9^th December, 2023, in Kasane, Republic of Botswana.
