Common questions
How do I convert a Shamsi date to Gregorian?
Type the Shamsi date as year/month/day — for example 1405/08/10 — in the Shamsi field. The Gregorian date, 2026-11-01, appears immediately along with the weekday. To convert the other way, type in the Gregorian field.
What is today’s date in the Persian calendar?
Today’s date in both calendars is shown at the top of the converter, using your device’s local date. After converting other dates, press Today to bring it back.
Why does adding 621 sometimes give the wrong year?
Because the Persian year starts at Nowruz (around 20–21 March), not on 1 January. From Nowruz to 31 December, the Gregorian year is the Persian year + 621; from 1 January until Nowruz it is + 622. The conversion guide explains the other common pitfalls.
Is 30 Esfand a valid date?
Only in leap years. In a common year Esfand has 29 days, and the converter tells you when a year is not a leap year. See how Persian leap years work.
Are the dates I enter stored or sent anywhere?
No. Conversion happens in your browser. Recent conversions are kept in this tab’s session storage and are cleared when that tab’s session ends. The privacy page has the details.
