The oldest liturgical year still kept

Zoroastrianism may hold the oldest religious calendar still in daily use. Its year is built around fire and the seasons, and around a set of named days: every day of the month and every month carries the name of a divine being, a yazata, and when the day-name and the month-name coincide the result is a Jashan, a feast in that being’s honour.

The year’s great structure is the six Gahanbars, seasonal festivals that celebrate the creation of sky, water, earth, plants, animals, and humankind in turn. Nowruz, the new year at the spring equinox, is the best known and most widely kept, a festival far older than the modern Iranian state that still observes it. Fire stands at the centre throughout, honoured in rites like the Three Great Fires, the legendary sacred fires of priest, warrior, and farmer.

What this calendar holds

One complication is built in. Zoroastrian communities never fully agreed on a single reckoning after the fall of the Persian empire, so several calendars (Fasli, Shahanshahi, and Qadimi) run a month or so apart, and the dates here follow one of them. Behind the variation is a liturgical year three thousand years deep, still turning on its sacred fires and the long war of light against the dark.

Common Questions

What is the Zoroastrian calendar?
One of the oldest liturgical calendars still in use, built around fire and the six seasonal Gahanbar festivals, with each day and month named for a divine being.
What is Nowruz?
The Zoroastrian and Iranian new year, celebrated at the spring equinox. It is one of the oldest festivals on Earth still kept, and is now observed well beyond Zoroastrian communities across the Persian world.
What are the Gahanbars?
Six seasonal festivals spread through the year, each celebrating one of the six creations (sky, water, earth, plants, animals, and people) in Zoroastrian cosmology.
Why do Zoroastrians have different calendar dates?
After the fall of the Sasanian empire the community lost a single shared reckoning, and three calendars (Fasli, Shahanshahi, and Qadimi) drifted apart. They now place the same festivals up to a month away from each other.
