Hijri and Gregorian dates on a wedding invitation
Many Gulf invitations carry the Hijri date and the Gregorian date side by side. It is simple once you know where the one-day differences come from and how to write the pair so that nobody doubts the day.
Why two dates
The Gregorian calendar runs diaries, flights and venues. The Hijri calendar, which is lunar, is the one many families use for occasions, and in Saudi Arabia the civil calendar is Umm al-Qura, a calculated Hijri calendar. Showing both lets every guest find the day in the calendar they trust.
In the UAE and Jordan, the Gregorian date usually leads and the Hijri date is added when the family wants it.
How to convert
Use the Umm al-Qura table, which is the published calendar for Saudi Arabia, or a converter built on it. Two known examples: 1 March 2025 was 1 Ramadan 1446 AH, and 20 November 2026 is 10 Jumada al-Akhirah 1448 AH.
Programming libraries that follow Umm al-Qura give the same answers as these examples, which is why many tools offer it. Dawati's editor does not convert dates for you: you type both dates in your wording.
The one-day difference
Umm al-Qura is calculated, while some communities begin a month when the new moon is sighted. The two can differ by a day, and a wedding date is the last place you want a doubt.
If your families follow moon sighting, write the Gregorian date and the weekday as the anchor. Guests rely on the weekday, so always print it.
How to write both
A common pattern is the weekday, the Hijri date, then the Gregorian one: الخميس ١٠ جمادى الآخرة ١٤٤٨هـ الموافق ٢٠ نوفمبر ٢٠٢٦م. In English write the weekday, the Gregorian date and the Hijri date in brackets.
Keep the same pattern everywhere: the card, the RSVP page, and your WhatsApp message.
Friday 20 November 2026 (10 Jumada al-Akhirah 1448 AH)
Evening and time zones
The Hijri day is counted from sunset, so a wedding that begins after Maghrib falls, by that count, on the next Hijri date. Most invitations print the date of the daytime civil calendar and do not explain this; if your families care, ask an elder which they expect.
For guests flying in, add the city to the time. Saudi Arabia is on UTC+3 all year, the UAE on UTC+4 and Jordan on UTC+3, with no daylight saving in any of them.
