Need the lunar Hijri calendar? Open the Hijri date converter
1900-2100The Shamsi (Jalali) calendar is the civil calendar of Iran and Afghanistan. Years usually start on Nowruz (1 Farvardin). This page converts both ways with weekday, leap-year notes and a day count to the next Nowruz. For the lunar Hijri calendar use the separate Hijri tool — this page stays on شمسی only.
Frequently asked questions
What is the Shamsi (Jalali) calendar?
Iran’s solar-year calendar. The year usually begins on Nowruz (1 Farvardin).
Is it the same as the lunar Hijri calendar?
No. Shamsi is solar; lunar Hijri is a moon-year calendar. Use the Hijri (lunar) date converter for قمری dates.
How do I convert to Gregorian?
Pick Shamsi → Gregorian, enter year-month-day (or Today) and read the Result card.
Can I convert Gregorian → Shamsi?
Yes — switch the direction control; both directions are supported.
Why does Esfand sometimes have 30 days?
Only in Jalali leap years. Otherwise Esfand has 29 days.
How do I know if a year is leap?
The result shows the year length / leap flag (Borkowski / jalaali algorithm).
Can I type Persian digits?
Yes (e.g. ۱۴۰۵). They are normalised to Latin digits.
When is Nowruz?
1 Farvardin. 1405 = 21 Mar 2026; 1406 = 21 Mar 2027 (algorithm).
What is the Nowruz countdown?
Whole days until the next 1 Farvardin. No ticking seconds.
Which date should I put on a visa form?
Most countries want Gregorian. Convert your Shamsi birth date and write the Gregorian result.
Which language are weekdays in?
Persian names on the fa page; the other locales use their own weekday names.
Does the time zone matter?
Only your device’s local calendar day is used; nothing is shifted to UTC. The date appears after the page loads in your browser.
Do old years (e.g. 1300s) work?
The practical range is about Gregorian 1900–2100; outside that you get a warning.
Why is there an Azerbaijani UI?
For Iranian/diaspora forms that still show Shamsi dates alongside Gregorian.
Is anything uploaded?
No. Conversion stays in your browser.
How is this different from قمری (lunar Hijri)?
قمری is the lunar Hijri calendar; this tool is شمسی / Jalali (solar). Use the Hijri date converter linked on this page for lunar dates.
How is this different from the site calendar?
The monthly calendar page shows a grid of days; this page converts a single date both ways across a wide year range.
Can I convert Hijri dates here too?
Not on this page — Shamsi only. Open the Hijri date converter from the link under the result for lunar dates.
