Nowruz 2027: date, time, and countdown

Planning around the next Persian New Year? Here’s the date for Nowruz 2027, why it lands when it does, and a live countdown.

Here’s how long until the next Nowruz, ticking live:

Why 21 March in 2027

Nowruz is pinned to the vernal equinox, the moment spring begins, observed at the reference meridian for Iran. The equinox drifts by about six hours each year and then snaps back when a leap day is added, so its Gregorian date moves between 20 and 21 March (source: timeanddate.com, March equinox). For example, in 2027 the equinox falls on 20 March in UTC but, in Iran Standard Time (UTC+3:30), the moment lands such that 1 Farvardin is 21 March — a clean illustration of why the local reference meridian matters.

For context, the surrounding years and the weekday each one falls on:

2027 is the third 21 March new year in a row. From 2028 the date slips back to the 20th, as it tends to around the leap years. The full mechanism is in why Nowruz isn’t always on the same Gregorian day.

The exact moment, and the noon rule that decides the date

The equinox is an instant, not a day. For 2027 it falls at 20:25 UTC on 20 March (source: timeanddate.com, March equinox).

The rule Iran’s calendar uses is about where that instant lands in Tehran: if the equinox occurs before noon Tehran time, that day is 1 Farvardin; if after, the new year starts the next day. In 2027 the instant is 23:55 in Tehran, still on 20 March — comfortably after noon, so Nowruz is the 21st.

That 23:55 is worth reading carefully, because it is easy to garble. The instant is late evening on the 20th in Tehran, not the 21st; some sites print it as a time on 21 March, which is the same arithmetic slipped by a day.

The same instant, around the world:

Everyone experiences the same moment; only the clock reading differs. So families in Sydney and Los Angeles mark the turn of the year nearly a full day apart on their own calendars.

2025 shows how fine the margin can be. That year the equinox hit 12:31 in Tehran — thirty-one minutes past noon. Half an hour earlier and Nowruz would have been 20 March instead of the 21st. A single year’s date can hinge on minutes.

One caveat about this site: the converter’s arithmetic follows the standard 33-year Jalali cycle, it does not compute the equinox astronomically. The instants above come from a published ephemeris, and for the years covered here the two agree on the date.

What Nowruz 2027 begins

21 March 2027 is 1 Farvardin 1406, the first day of the Persian year 1406. From that day, the year number ticks over, so a date written in late March 2027 could be 1405 or 1406 depending on which side of Nowruz it falls. If you need to place a specific date, see what year is it in the Persian calendar or use the converter.

Marking the day

Nowruz is celebrated with the haft-sin table, spring cleaning, family visits, and Sizdah Bedar on the thirteenth day. These are cultural traditions practised in varied forms across the regions that observe Nowruz. The background is in what is Nowruz.

How many days until Nowruz 2027?

The countdown near the top of this page answers that to the second. It reads your device clock and counts down to 21 March 2027, so the number is current whenever you look.

To count from a different day, such as a booking or a deadline, put both dates into the date difference calculator. It takes Shamsi or Gregorian dates and gives the gap in days, in weeks, and in working days. It runs on your device, like the converter, so there’s nothing to wait on.

So: Nowruz 2027 is Sunday 21 March, starting year 1406. Keep an eye on the countdown above, or convert any date around it.
