How the conversion works The tool covers Gregorian years 1900 to 2100. Hijri dates use the Umm al-Qura calendar, the official calendar of Saudi Arabia, where months have 29 or 30 days set in advance. Persian dates use the Solar Hijri calendar used in Iran and Afghanistan, where the year starts at the March equinox (Nowruz). Both use the calendar data built into your browser. If you enter a day that does not exist, such as the 30th of a 29-day Hijri month, the tool tells you instead of guessing. Check important dates. In many countries Islamic months start when the new moon is sighted, so a local Hijri date can be one or two days off the Umm al-Qura date. For visas, contracts and official papers, check the date with the office that issued the document. -nu-latn pc-resu
