The calendar behind every official date in Saudi Arabia.
Umm al-Qura is the Hijri calendar computed by the Saudi government and used for official documents — iqama expiry, contracts, court dates, and public holidays.
A Hijri year has 12 lunar months and is about 11 days shorter than a Gregorian year. That's why Hijri dates drift earlier through the seasons every year.
Iqama and contract dates are often written in Hijri while payroll and travel run on Gregorian. Converting correctly avoids missed renewals and expiry surprises.
