Persian Calendar 1406 (2027–2028): What’s Confirmed So Far
Aktie
Persian year 1406 begins on Sunday, March 21, 2027, and ends on Sunday, March 19, 2028. It is a 365-day Solar Hijri year. That makes it possible to map the month boundaries and fixed solar observances now—but not every official holiday.
There is an important status note for anyone planning far ahead. As of July 30, 2026, the University of Tehran Calendar Center’s 1406 page says the official calendar is still “in progress.” This guide therefore separates dates that follow directly from the solar calendar from government closures and lunar religious observances that still require an official announcement.
Persian calendar 1406 at a glance
- First day: 1 Farvardin 1406 = Sunday, March 21, 2027
- Last day: 29 Esfand 1406 = Sunday, March 19, 2028
- Length: 365 days
- Leap year: No; Esfand has 29 days
- Gregorian span: March 21, 2027–March 19, 2028
Why does 1406 start on March 21, 2027?
The Solar Hijri calendar is tied to the March equinox rather than a fixed Gregorian date. Timeanddate’s explanation of the Persian calendar notes that the year begins at the midnight closest to the vernal equinox, using the Iran Standard Time meridian at 52.5 degrees east.
In 2027, the March equinox in Tehran occurs at 11:54 p.m. IRST on March 20. The nearest midnight is the start of March 21, so 1 Farvardin 1406 falls on Sunday, March 21. This is a useful example of why Nowruz can fall on March 20 in one year and March 21 in another.
Nowruz literally means “new day.” UNESCO describes it as an ancestral celebration of spring and nature’s renewal, observed with family visits, special meals, new clothes, rituals, and gift-giving. The United Nations recognizes March 21 as the International Day of Nowruz, but the precise start of the Iranian calendar remains astronomical.

For converting an individual birthday, anniversary, or historical date, use Tute’s Persian date converter guide rather than estimating by month position. The Gregorian date paired with a Persian date can shift from one year to the next.
Useful fixed cultural dates in 1406
The following are solar-calendar observances, so their positions can be planned from the month map above. They are cultural dates; this list should not be read as a final schedule of statutory public holidays.
- Nowruz: Sunday, March 21, 2027 (1 Farvardin)
- Sizdah Bedar: Friday, April 2, 2027 (13 Farvardin). Encyclopaedia Iranica identifies 13 Farvardin as the close of the Nowruz festive period.
- Yalda Night: Tuesday evening, December 21, 2027, leading into 1 Dey. It is the winter-solstice night and is traditionally spent with family, fruit, nuts, poetry, and conversation.
- Sadeh: Sunday, January 30, 2028 (10 Bahman). Iranica’s survey of Khorasan traditions places Sadeh on the tenth of Bahman, around January 30.
- Chaharshanbe Suri: Tuesday evening, March 14, 2028, before the last Wednesday of 1406. Encyclopaedia Iranica defines the festival by the eve of the final Wednesday of the Persian solar year.
What is not confirmed yet?
Iran’s finalized official calendar normally identifies government closures, nationally approved commemorations, and religious dates calculated in the lunar Hijri calendar. Those lunar observances move through the solar year, and their final civil dates should not be guessed.
Until the Calendar Center publishes the completed 1406 calendar, treat circulating lists of official holidays with caution. A careful planner can safely use the month boundaries and fixed solar dates above while leaving lunar observances and workplace closures unconfirmed.
Planning 1406 in the United States or Canada
For diaspora families, a dual-calendar approach works best:
- Record important family dates in both Persian and Gregorian forms.
- Put Nowruz and Sizdah Bedar on shared calendars early, especially if a gathering needs a weekend venue.
- Keep cultural observances separate from employer, school, provincial, state, or federal holidays.
- Recheck official Iranian holiday dates after the University of Tehran Calendar Center releases the completed 1406 calendar.
- Add the time zone to any virtual tahvil-e sal gathering; the astronomical moment is simultaneous, but the clock time differs across Tehran, Toronto, Vancouver, Los Angeles, and New York.
If you prefer the year in front of you rather than buried in an app, Tute’s Limited Edition Persian Hijri Shamsi Desk Calendar 1406 pairs the Persian year with Iranian landmark artwork for everyday planning.
