Date Converter
Switch between Gregorian and Jalali in one click. Leap years are handled for you.
Are leap years handled?
Yes. The converter uses the full calendar algorithm, not a fixed offset, so leap years on both sides are correct, including the rare Jalali leap patterns.
What date range works?
Any modern date from the 17th century onward converts correctly, which covers every document, certificate and contract you will meet.
Is my date stored?
No. The conversion runs entirely in your browser. Nothing is sent or saved.
