Frequently asked questions
Short answers to the things learners ask most about this tool.
What is the Umm al-Qura calendar?
Umm al-Qura is the calculated Islamic calendar used in Saudi Arabia. It defines month lengths and year lengths in advance, so software can convert dates without waiting for a local moon sighting.
Why can the Hijri date differ by a day?
Local communities may begin a month after an actual moon sighting, while Umm al-Qura uses a fixed calculation. As a result, the civil Hijri date can be one day before or after the date announced in a particular country.
Can I convert Hijri to Gregorian as well?
Yes. Change either side and the other updates immediately. You can pick a Gregorian date with the date field or choose a Hijri day, month, and year with the selectors.
What date range is supported?
The converter supports 1900–2100 CE, roughly 1317–1524 AH. Dates outside that range are rejected rather than approximated.
Is the Hijri converter free and private?
Yes. It is free, needs no account, and runs entirely in your browser. No date you enter is uploaded.
