Why today matters

Today's Zoroastrian day, in the most widely-used Shahanshahi reckoning, is sacred to Asha Vahishta (Ardibehesht / Ordibehesht) — the divine spirit of truth, right order, and the fire that sustains creation. Each day of the Zoroastrian month is named after a different yazata (divine spirit), and prayers (khshnaothra) appropriate to that yazata are recited at the day's five sacred times (gah). The Zoroastrian calendar is the source from which the Persian (Shamsi) calendar took its twelve month names — the modern Iranian months Farvardin, Ordibehesht, Khordad, Tir, Mordad, Shahrivar, Mehr, Aban, Azar, Dey, Bahman, and Esfand are all Zoroastrian yazata names preserved into the Islamic era.

Ushtā ahmāi yahmāi ushtā kahmāi-cīt — "Happiness be to him through whom happiness comes to others." — From the Gathas, Yasna 43:1

How we compute this

Zoroastrian (Shahanshahi / Kadmi / Fasli) is a solar calendar. Each year contains 365 days (Shahanshahi and Kadmi); 365.2422 (Fasli, with leap years), with each month averaging 30 days + 5 (or 6 in Fasli) intercalary Gatha days. Years are counted from 16 June 632 CE — accession of the last Sasanian Persian emperor, Yazdegerd III (era: AY — Yazdegerdi Era).

The Zoroastrian calendar is one of the oldest continuously-used calendar systems in the world, with roots reaching back over 3,000 years to the time of the prophet Zarathushtra (Zoroaster). The current Yazdegerdi era takes its name from Yazdegerd III, the last emperor of the Sasanian Persian Empire, whose coronation in 632 CE became year 1 of the era — the Sasanian Empire fell to Arab Muslim armies just nine years later, and the Zoroastrian community has counted from that moment of crisis ever since. Today, three competing variants of the calendar exist: Shahanshahi ("imperial", used by most Parsis in India) keeps the original Sasanian leap-year-less form, so it has drifted by about a month from the seasons. Kadmi ("ancient", used by a smaller Parsi community and some Iranis) is one month ahead, claiming to preserve the older sequence. Fasli ("seasonal", introduced in 1906 by the priest Khurshedji Cama) adds leap years and locks the new year to the spring equinox (Nowruz), making it the most astronomically accurate of the three.

Used by: ~110,000 Zoroastrians worldwide — the Parsis of India, the Iranis of Iran and Iran's emigré communities. Regions: India (Parsi communities in Mumbai, Gujarat), Iran (Yazd, Kerman, Tehran), and a global diaspora across the US, UK, Canada, Australia.

Frequently asked

What is the Zoroastrian date today?

Today's Zoroastrian date in the Shahanshahi calendar is Mohor Ardibehesht, year 1395 AY. (In the Kadmi calendar it is one month ahead; in the Fasli calendar it differs based on the seasons.)

Why are there three different Zoroastrian calendars?

After Yazdegerd III's death in 651 CE, the Zoroastrian community fractured between those who fled to India (the Parsis) and those who remained in Iran (the Iranis). Centuries of geographic separation produced a one-month drift between the calendars used in each community. The Shahanshahi ("imperial") calendar is used by most Parsis in India. The Kadmi ("ancient") calendar, one month ahead, is used by a minority of Parsis and some Iranis who consider it more authentic. In 1906, the priest Khurshedji Rustomji Cama introduced the Fasli ("seasonal") reform — adding leap years and locking Nowruz to the spring equinox — and many modern Zoroastrians have adopted it.

Why does the year count from 632 CE?

The Yazdegerdi era (AY) is named after Yazdegerd III, the last Sasanian Persian emperor, who was crowned in June 632 CE. Just nine years later, in 651 CE, his empire fell to the Arab Muslim armies and Yazdegerd was killed in flight near Merv. The Zoroastrian community has counted from his coronation ever since — a chronological monument to the empire that protected the religion for four centuries.

How is the Zoroastrian month structured?

A Zoroastrian month has 30 days, each named after a yazata (divine spirit): the 1st (Hormazd) is sacred to Ahura Mazda; the 2nd (Bahman) to Vohu Manah (good thought); the 3rd (Ardibehesht) to Asha Vahishta (truth), and so on. After the 12 months, 5 additional days (the Gatha days, named after the five Gathas of Zarathushtra) complete the year — bringing the total to 365. The Fasli variant adds a 6th Gatha day in leap years.

What is Nowruz to Zoroastrians?

Nowruz — "New Day" — is the Zoroastrian New Year, falling on 1 Farvardin at the spring equinox. While Nowruz is celebrated across the broader Persian cultural world (Iran, Afghanistan, Tajikistan, the Kurdish regions, etc.), it originated as a Zoroastrian festival celebrating the rebirth of creation in spring and the triumph of Ahura Mazda over Angra Mainyu. The festival is inscribed on UNESCO's list of Intangible Cultural Heritage of Humanity (2009).

How many Zoroastrians are there today?

Approximately 110,000–120,000 worldwide, with the largest community being the Parsis of India (about 60,000, concentrated in Mumbai and Gujarat). Iran retains about 25,000 Zoroastrians, mostly in Yazd, Kerman, and Tehran. The diaspora — North America, the UK, Australia, the Gulf states, and elsewhere — totals roughly 30,000. Despite small numbers, the community has had outsized influence on world culture: Persian mythology and language, the Iranian Solar Hijri calendar, the seven-day week, and several elements of Abrahamic religious thought all trace partly to Zoroastrian sources.
