Hijri Date Converter

The Umalqura calendar — the official calendar of Saudi Arabia and the one built into phones and operating systems (the Intl islamic-umalqura calendar). Dates here will match what your phone shows. In some countries the local moon-sighting announcement can differ by a day; religious observance follows your local announcement.

Open the converter above — the Gregorian side starts on today, and the matching Hijri date is shown immediately. For example, 18 February 2026 was 1 Ramadan 1447.

Hijri months follow the moon: a month ends when the new crescent begins the next one, so months alternate between 29 and 30 days and a Hijri year is about 354 days — roughly 11 days shorter than a solar year. That is why Ramadan moves earlier through the seasons over the years.

Some months in some years have 29 days, so a 30th day does not exist for them. The converter checks the real month length for the year you entered and tells you instead of guessing a date.
