Hijri & Gregorian Age Calculator
Enter your birth date in Hijri or Gregorian and get your age in detail: years, months, days, and total days and hours — in both calendars simultaneously.
How to Calculate Your Age Precisely in Hijri and Gregorian?
The calculator displays detailed results in years, months, days, and minutes in both the Hijri and Gregorian calendars. Hijri calculations rely on official Umm al-Qura calendar data, while Gregorian calculations use internationally adopted standards.
Why Does Age Differ Between the Two Calendars?
The lunar Hijri year (approximately 354 days) is shorter than the solar Gregorian year (365 days), so your age in Hijri appears about 3% higher. This is not a calculation error—it is the natural difference between the two calendars. If you want to convert your birth date between the two calendars directly, use the date converter.
Retirement Age: Hijri or Gregorian?
In many countries and institutions, the retirement age is calculated based on the Gregorian calendar. If your employment contract specifies reaching sixty Gregorian years, that is approximately equivalent to 61 years and 9 months in the Hijri calendar since the Hijri year is shorter. This calculator helps you know your exact age in both calendars to plan your career path precisely.
A Note on Accuracy
Results are accurate within the supported range of the Umm al-Qura calendar (1343–1500 AH). Dates outside this range may rely on mathematical approximations. You can also calculate the age difference between you and another person directly.
Frequently Asked Questions
Why is my Hijri age higher than my Gregorian age?
Because the Hijri year is approximately 11 days shorter than the Gregorian year. As this difference accumulates annually, the number of Hijri years becomes larger for the same period of time.
Can I calculate my age from a Hijri date directly?
Yes. Select the Hijri calendar then enter your Hijri birth date. You will get your age in both Hijri and Gregorian calendars.
How do I find my Hijri birthday?
Enter your Gregorian birth date in the calculator and the result will include its Hijri equivalent. You can also use the <a href="/en/date-converter">date converter</a> for more details.
