Hijri to Gregorian Date Converter (Dual Direction)
A fast, reliable date conversion utility designed for professionals, expats, and legal administrators dealing with Middle Eastern records.
Gregorian Result (Sunday)
How It Is Calculated (Formula & Law)
Formula: Astronomical Julian Day conversion synced with the Umm al-Qura lunar database.
Governing Standard / Law: Official calendar conversion models used by Saudi administrative and judicial bodies.
The Need for Precision Date Conversion
Converting between the Hijri and Gregorian calendars is a routine necessity across Saudi Arabia and the GCC. Expatriates frequently handle documents—such as residency permits (Iqama), birth certificates, lease agreements, and judicial deeds—that record dates solely in the Hijri calendar.
Avoiding the Common 1-2 Day Conversion Errors
Simple mathematical formulas (such as dividing by 1.03) often produce errors of one or two days because lunar months fluctuate irregularly between 29 and 30 days. Hasiba utilizes the official Julian day count mapped against validated Umm al-Qura observations.
Practical Applications
- Immigration & Visas: Converting Iqama expiry and entry visa validities.
- Human Resources: Calculating exact probation periods, service duration, and leave entitlements.
- Contract Management: Ensuring commercial contracts with Hijri termination clauses match banking and accounting cycles.
Practical Birth Date Conversion
Scenario: An expat needs the Gregorian date for a child born on 10 Rajab 1415 AH.
Calculation: Translating year 1415, month 7, day 10 using official Umm al-Qura alignment.

Is this conversion aligned with the Saudi Absher and Qiwa platforms?▼
Yes, our calculations use the exact Umm al-Qura astronomical lunar standard utilized across official Saudi government electronic portals.
Why do the Hijri and Gregorian calendars differ in year length?▼
The Hijri year consists of 12 lunar months totaling 354 or 355 days, while the solar Gregorian year totals 365 or 366 days, creating an annual variance of around 11 days.
Why do some generic conversion formulas give dates off by 1 or 2 days?▼
