How the persian (solar hijri) calendar converter works
The Persian, or Solar Hijri, calendar is one of the most astronomically accurate in use: its year begins at the exact moment of the spring equinox (Nowruz, around 20–21 March), and its leap-year pattern tracks the tropical year more closely than the Gregorian rule. This converter uses the calendar from your browser's ICU data and inverts it exactly. Years are marked AP (Anno Persico) or SH, counted, like the Hijri calendar, from 622 CE — but solar, so it stays fixed against the seasons.
Don't confuse it with the Islamic (Hijri) calendar: both count years from 622 CE, but the Persian calendar is solar (365/366 days, fixed seasons) while the Islamic one is lunar (354 days, drifting). That is why their year numbers differ by hundreds — a Persian year is currently around 1404, an Islamic year around 1447.
Frequently asked questions
What is the Persian calendar also called?
The Solar Hijri calendar, or Jalali calendar. It is the official calendar of Iran and Afghanistan, and among the most accurate solar calendars in use.
When does the Persian year start?
At the vernal (spring) equinox — Nowruz — which falls on 20 or 21 March in the Gregorian calendar. The year is astronomically anchored to the equinox, not a fixed date.
How is it different from the Islamic Hijri calendar?
Both count from 622 CE, but the Persian calendar is solar (365–366 days, seasons fixed) and the Islamic calendar is lunar (about 354 days, drifting ~11 days earlier a year). Their year numbers differ by several decades and grow apart over time.
What does AP mean?
Anno Persico — the Persian year count. It shares its epoch (622 CE) with the Hijri calendar but, being solar, its year number differs.
Is this computed locally?
Yes — the Persian calendar ships in your browser's ICU data, so the conversion is local and works offline.
