New year in other calendars
The day the year turns is not the same in every calendar. And what fixes that day is astronomy in some of them and nothing but an era count in others.
- Next new year
- Computing…
The dates in this table are Gregorian dates with no time of day — a calendar day is a date, not an instant. So, like the lunisolar table, the Korean and English pages show the same one. A religious day begins after sunset, but what is listed here are the dates of the civil tables these calendars settled into.

The same year is a different number in each calendar
What year each calendar reads on 1 January and 31 December 2026. Only the calendars whose year starts on 1 January show the same number twice — and only those have a constant offset from the Gregorian year.
| Calendar | 1 January | 31 December | Offset from Gregorian |
|---|---|---|---|
| Korean lunisolar | no number (cyclic name) | no number (cyclic name) | changes mid-year |
| Hijri | 1447 | 1448 | changes mid-year |
| Hebrew | 5786 | 5787 | changes mid-year |
| Solar Hijri | 1404 | 1405 | changes mid-year |
| Indian Saka | 1947 | 1948 | changes mid-year |

A year is not the same length in every calendar
A purely lunar calendar runs 354 to 355 days, so its new year arrives about eleven days earlier each Gregorian year. One that keeps step with the seasons through a leap month runs anywhere from 353 to 385. Solar calendars run 365 to 366. The table below shows the range within the three years in the data, which does not reach either end of those rules.
| Calendar | New year | Year length |
|---|---|---|
| Korean lunisolar | Korean New Year | 354–384 days |
| Hijri | Islamic New Year | 354–355 days |
| Hebrew | Rosh Hashanah | 354–385 days |
| Solar Hijri | Nowruz | 365 days |
| Indian Saka | Saka New Year | 365 days |
| Ethiopian | Enkutatash | 365–366 days |
| Coptic | Nayrouz | 365–366 days |
Nowruz is fixed by astronomy
The Solar Hijri new year is the day of the vernal equinox if that moment falls before noon in Tehran, and the next day otherwise. This site computes the equinox from VSOP87D, so it can retrace that rule directly — over thirty-one years it never disagreed with the internationalisation tables, and the two branches of the rule fired sixteen and fifteen times.
Our lunisolar calendar and the internationalisation tables agree
This site computes the lunisolar calendar itself — new moons from Meeus chapter 49, solar terms from VSOP87D. The Dangi calendar in the internationalisation tables is an entirely separate implementation, and across the 37 months in the data not one month-start differs. Had either been wrong, it would have shown here.
The whole sky Holidays in other countries
The dates come from the internationalisation tables (ICU) in the browser and in Node; we freeze them and check them. We test that each year length falls inside that calendar’s rule, that Nowruz agrees with the equinox computed here, and that our own lunisolar new moons give the same answer.
