Hijri Gregorian Converter

The tool uses an arithmetic civil Hijri calendar model.

That means it can differ by a few days from officially sighted religious calendars.

It is useful for planning, publishing workflows, and approximate date matching across calendars.

For official or religiously sensitive dates, verify against the relevant local authority.

An arithmetic Hijri model treats month lengths through a computable pattern, which gives fast and consistent approximate results.

That makes it useful for planning and comparison, but it does not replace local moon-sighting calendars or official religious calendars.

Hijri month starts can vary by country, institution, and observation method, so a difference of a few days should be expected.

For holidays, worship, official filing, or legally sensitive dates, the relevant authority calendar should be checked separately.

The converter is useful for content calendars, archive labels, travel preparation, and multilingual publishing plans.

When comparing many dates, using the same conversion model consistently reduces drift inside lists and tables.

The content was written against technical references such as Unicode CLDR calendar data and Nager.Date Hijri calendar notes.

Results are approximate calendar conversions and should not be used as the only source for religious, official, or financial decisions.
