In Saudi Arabia, the Hijri calendar is the official calendar used in all government documentation. National ID cards, passports, Iqama (residency permits), birth certificates, and civil registry records all include the birth date in the Hijri calendar alongside or instead of the Gregorian date. When completing government, university, or employment forms, you may be asked to write your birth date directly in Hijri. Knowing your Hijri birth date accurately matters — especially when dealing with government bodies that follow the official Umm Al-Qura calendar, which can differ by one day from a standard astronomical calculation in certain cases.
Suppose someone was born on 15 August 1995. Converting this date to Hijri using astronomical calculation gives approximately 18 Rabi al-Awwal 1416 AH, a Tuesday. This means this person's Hijri birthday falls on 18 Rabi al-Awwal each Hijri year — and because the Hijri (lunar) year is about 354 days while the Gregorian (solar) year is 365 days, this Hijri date shifts earlier by roughly 10–11 days each Gregorian year. Try the converter above with your own birth date to get an accurate, personalized result.
In most cases, yes — but it may differ by one day in certain circumstances. This is because Saudi government bodies use the Umm Al-Qura calendar published by KACST, which is based on actual crescent moon visibility data rather than a purely mathematical formula. If the Hijri birth date on your official Saudi documents differs by one day from this tool's result, that is normal and not an error — both dates are correct from different calculation methods. For a result that matches official documents exactly, use the Umm Al-Qura Calendar Converter, which uses real KACST data and shows you any difference.

As a rough estimate, the Hijri year equals the Gregorian year minus 622, multiplied by approximately 33/32 (since the Hijri year is about 11 days shorter). However, this is only an approximation.
