Which Hijri calendar does this tool use?

It uses the Umm al-Qura calendar, the official civil Islamic calendar of Saudi Arabia, via the browser's built-in islamic-umalqura calendar. This is the most widely used administrative Hijri reckoning. Other regions occasionally differ by a day based on local moon sighting.

Why might the Hijri date differ by a day from my local calendar?

Hijri months begin with the sighting of the new crescent, which varies by location and method. Umm al-Qura uses an astronomical calculation, so a sighting-based local calendar can land one day earlier or later. Treat the result as the standard civil reference.

What are the Arabic month names shown?

Gregorian months use the Levantine Arabic forms (يناير, فبراير, مارس…). Hijri months are the twelve Islamic months: محرّم, صفر, ربيع الأول, ربيع الآخر, جمادى الأولى, جمادى الآخرة, رجب, شعبان, رمضان, شوّال, ذو القعدة, ذو الحجة.

Are Eastern-Arabic numerals required?

No. Eastern-Arabic numerals (٠-٩) are common across the Mashriq, while Western digits (0-9) are standard in the Maghreb. Toggle whichever your audience expects; the spelled-out month and weekday stay the same either way.

Does any of my data leave the browser?

No. The conversion uses your browser's own internationalization engine. Nothing is sent to a server, so the dates you enter stay completely private on your device.

This tool turns a plain calendar date into fully written-out Arabic, giving you both the Gregorian (الميلادي) and Hijri (الهجري) forms with the weekday and month names spelled out and the day and year in Eastern-Arabic numerals.

How it works

The Gregorian rendering looks up the Arabic name for the weekday and month and formats them as الأحد، ٤ يونيو ٢٠٢٦. The Hijri rendering relies on the Unicode internationalization calendar islamic-umalqura, which your browser ships with. Given a Gregorian date, it returns the corresponding Hijri day, month, and year:

weekday = ["الأحد", "الإثنين", … "السبت"][date.getUTCDay()]
hijri   = Intl.DateTimeFormat("en-u-ca-islamic-umalqura", …)
output  = `${weekday}، ${day} ${hijriMonth} ${year} هـ`

The date is built in UTC so that your local time zone never shifts the day across midnight.

Example and notes

The Gregorian date 2026-06-04 renders as الخميس، ٤ يونيو ٢٠٢٦ and, in the Hijri calendar, as roughly الخميس، ١٨ ذو الحجة ١٤٤٧ هـ. The trailing هـ abbreviation marks a Hijri year, equivalent to writing “AH” in English. Because Hijri month boundaries depend on crescent visibility, the Umm al-Qura result can differ by a day from a sighting-based local calendar — that is expected, and Umm al-Qura is the standard civil reference for documents and scheduling.
