How the date converter works

The result appears automatically once the year, month and day are complete, and you can copy it with its calendar name. The date values you enter are not sent to a server.

- 03Copy the result
The result appears automatically when the date is complete and can be copied with one click.
Conversion accuracy
- The converter uses an arithmetic method based on the Julian day number. This is a common tabular method, not an official astronomical calendar.
- The result can differ by one day from Umm al-Qura or from a locally sighted month start.
- The Hijri day list follows an alternating 30/29 pattern, so the last day of Dhu al-Hijjah can differ in leap years.
- For official or religious dates, check with the relevant authority or your adopted calendar before relying on the result.
Frequently asked questions
Is the result officially approved?
The result is arithmetic and is meant for comparison and everyday use, not as an official reference. Check with the relevant authority for official or religious dates.
Why does another site show a different day?
Converters may use different methods or references for the Hijri calendar, or a different local month start, so a one-day difference is expected.
What range of years is available?
The list shows fifty years before and fifty years after the current year in the selected direction, excluding non-positive years.
Is the conversion automatic?
Yes. Once the year, month and day are selected, the result appears immediately with no extra button.
Are the dates I enter sent to a server?
No. The conversion runs in the browser and the date values are not sent. A generic usage event is logged so the tool appears on the site dashboard.
