How accurate is this converter?
The conversion relies on the digital Umm al-Qura calendar (the same source used in the site's age calculator), and is accurate for everyday use. It may differ by one day from sources relying on actual moon sighting for some months — for precise religious occasions, it's best to confirm with an official source.
Why did some Hijri months show only 29 days?
The Hijri month ranges between 29 and 30 days depending on the actual lunar cycle, unlike fixed Gregorian months. If you select day 30 for a month that only has 29 days, the calculator automatically uses the last valid day and notifies you of this.
Can I convert a future date?
Yes, the lists cover dates from the year 1930 to 2050 Gregorian (and their Hijri equivalents), past and future.
Is my data saved or shared?
No, all conversion happens inside your browser only and nothing is sent to our servers.
What's the difference between this calculator and the age calculator?
The age calculator computes your age from your birth date until today. This calculator converts any single date between the two calendars, unrelated to age — useful for occasions, contracts, and official appointments.
