About the Hijri to Gregorian Converter
Enter any Hijri (Islamic) date — day, month and year AH — and this tool finds the exact matching Gregorian date. It supports the Umm al-Qura calendar used officially in Saudi Arabia as well as the two classic tabular arithmetic calendars, and it tells you the weekday and how many days away the date is from today.
This is the quickest way to answer questions like 'When is 1 Ramadan 1448 on the Western calendar?' or to convert a Hijri birth date on an identity document into its Gregorian equivalent for forms and applications. A moon-sighting adjustment of up to two days either way lets you fine-tune the result to match your local community's observed calendar.
The converter works by searching real calendar data built into your browser rather than a rough formula, so the method you pick is respected exactly. It is free, instant and private — nothing you type leaves your device.

Frequently Asked Questions
How accurate is the Hijri to Gregorian conversion?
For the method you select, it is exact — the tool searches your browser's built-in Islamic calendar data for the Gregorian day whose Hijri representation matches your input precisely. Any remaining uncertainty comes from moon sighting practice, which the adjustment option lets you compensate for.
Why do some Hijri months have 29 days and others 30?
A lunar month averages about 29.53 days, so Hijri months alternate between 29 and 30 days. In the Umm al-Qura calendar the length follows astronomical new-moon calculations; in tabular calendars the lengths alternate by rule with a leap day added to Dhu al-Hijjah in leap years. If you enter day 30 of a 29-day month, no match exists and you'll be asked to check the date.
Which method should I use for official Saudi documents?
Use Umm al-Qura — it is the calendar printed in Saudi government records, and most Gulf-region institutions follow it. Tabular calendars are mainly used in historical scholarship and software that needs a purely arithmetic, timezone-independent calendar.
Can I find out when Ramadan or Eid falls in a future year?
Yes — enter 1 Ramadan (or 1 Shawwal for Eid al-Fitr, 10 Dhu al-Hijjah for Eid al-Adha) with the year AH you care about, and the tool returns the expected Gregorian date. Remember that the actual observance may shift a day depending on the crescent sighting in your region.
What Hijri years does the tool accept?
Anything from 1 AH up to roughly 9666 AH, with days 1-30 and all twelve months. Very distant dates convert mathematically fine but, as with all calculated calendars, the further you go the more they should be treated as approximations of what will actually be observed.
