Festivals of Light

Iranian festivals follow the solar year — a tradition that long predates the Islamic lunar calendar and was preserved through every dynastic change. Today these celebrations are inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity and are shared from Tajikistan to Turkey, from Iraqi Kurdistan to western India.

Shab-e Yaldā — the night of birth — marks the winter solstice and the birth of the new sun. Families gather at the grandparent's home, set out a long red sofreh, and stay awake until dawn around bowls of pomegranate and slices of watermelon kept since summer. Hafez is opened at random and his verses are read as personal augury. The tradition predates Christianity; the Roman cult of Sol Invictus and the date of Christmas itself are believed by many historians to have Mithraic, ultimately Iranian, origins.

Nowruz is now celebrated as a national holiday in eleven countries — Iran, Afghanistan, Tajikistan, Uzbekistan, Kazakhstan, Kyrgyzstan, Turkmenistan, Azerbaijan, Iraq, Georgia (Tbilisi), and increasingly in India and Turkey. The United Nations officially recognised 21 March as International Nowruz Day in 2010. Yalda Night was inscribed by UNESCO in 2022 as shared Iranian–Afghan intangible heritage.

Once second only to Nowruz in importance, Mehregān celebrates Mithra (Mehr) — the Iranian divinity of light, oath, contract, and the friendship that holds human society together. The Achaemenids made it the great autumn festival of the empire; in the Tārīkh-e Beyhaqi we read of Sasanian and Ghaznavid kings receiving foreign embassies on the day of Mehregan and exchanging gifts of pomegranates, walnuts, dried fruits, rosewater and silk. The table is set with a mirror, the holy book, white-then-violet cloth, and a small dish of senjed — the fruit Mithra is said to have made fragrant.

Sadeh — literally "hundred" — falls fifty days before Nowruz and marks the discovery of fire by the mythic king Hushang. According to the Shahnameh, Hushang hurled a stone at a serpent, missed, and the spark struck flint instead of beast: thus humanity won fire. On Sadeh eve, every Zoroastrian community in Yazd, Kerman and the diaspora gathers around tall bonfires of cypress and pomegranate wood, sings the Avestan Ātash Niyāyesh in praise of the flame, and shares the long meal that follows. The custom is attested unbroken from the Sasanian court down to the Yazdi villages of today — perhaps the oldest documented continuous fire-festival in the world.

On the thirteenth of Tir (early July) Iranians celebrate Tirgān, the festival of rain and harvest in honour of Tishtrya, the Zoroastrian divinity of rain and the star Sirius. The myth is preserved in the Tištar Yašt: Tishtrya, in the form of a white stallion, fights the demon of drought Apaosha at the shore of Lake Vourukasha. Modern Iranians celebrate by throwing water at one another, tying rainbow-coloured silk wristbands (tir o bād) to be cut and floated downriver ten days later, and reciting the augury-poems of the Fāl-e Kūzeh ("the omen of the jug") — drawing small objects from a clay pot of water while a child recites couplets.

The modern Iranian solar calendar — the most accurate civil calendar still in use — divides the year into twelve months whose names preserve those of the Zoroastrian yazata, the heavenly powers each charged with a domain of creation. Six 31-day months of spring and summer are balanced by five 30-day months of autumn and winter, with a final 29- or 30-day month closing the year.

Nowruz is celebrated from the Kurdish villages of the Zagros to the Tajik mountains of Pamir, and along the way it picks up a hundred local accents. In the Kurdish heartlands of western Iran, families ascend the high pastures on Nowruz morning for the festival of Newroz, with great mountain-top bonfires and the line-dance of halparkê. The Turkmen of Golestan stage horse-races on Sizdah Bedar; the Lori of the central Zagros prepare a special bread-soup called āsh-e reshteh-ye Nowruzi; in Tajikistan, Nowruz is opened with the steaming sumalak-cooking vigil of women through the night before the equinox.

Every Iranian festival has its own soundtrack. Nowruz arrives with the song of Hāji Firuz, the red-clad herald of spring who dances through the streets with his tambourine. Chaharshanbe Suri is the night of the daf and the setar by the fire. Mehregan's table-setting is accompanied by the kamāncheh bowed-fiddle, and Yalda by the slow chanting of Hafez. Most regional festivals close with a specific dish: kuku-sabzi on Nowruz, āsh-e reshteh on Sizdah Bedar, fesenjān on Yalda, kheer and walnut bread on Sadeh.
