About this tool

The Hijri calendar is lunar: 12 months of 29–30 days, about 354 days a year. This converter uses the standard tabular (civil) conversion used by most date libraries, computing through the Julian day number so both directions stay consistent. Because real-world Hijri dates are confirmed by moon sighting, printed calendars can differ by ±1 day — the tool states this honestly rather than pretending to false precision.

FAQ

Why can the result differ by a day from my calendar?

Official Hijri dates follow actual moon sighting; the tabular calendar is a fixed arithmetic approximation. A ±1 day difference is normal and expected.

Which years are supported?

Any reasonable year in both calendars — the conversion is mathematical, not a lookup table.

Is anything stored?

No. The conversion runs entirely in your browser.
