How to use this calculator
Select a direction and enter a Gregorian date or numeric Persian year, month and day. Check the returned method and weekday.
Uses the browser ICU Persian calendar for Gregorian 1900-2100. This is not a selectable 2820-year arithmetic-cycle implementation; national calendar announcements are separate reference material.
A worked example
March 20, 2024 corresponds to Persian 1403-01-01. November 4, 2026 corresponds to 1405-08-13.
Is Solar Hijri the same as the Islamic lunar calendar?
No. The Persian calendar is solar. The Hijri Date Converter provides separately named Islamic lunar methods.
Further reading: ICU calendar methods. Your entered rules determine this result.
Which calendar and years are supported?
Gregorian input coverage is 1900-2100 unless the method states a narrower range. Results explain calendar conventions and local date boundaries. Astronomy uses a level horizon at sea level. CSV, print and copy retain the result rules; calendar files contain only calculated events. Nothing is scheduled automatically.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
