Calculating age in Hijri and Gregorian using Umm al-Qura calendar

What is an age calculator in the Hijri and Gregorian calendars?

The Hijri and Gregorian age calculator helps you determine your age accurately based on your birth date, whether you use the Gregorian or Hijri calendar. The tool calculates your age in years, months, and days, and displays additional information such as the day of birth, the number of days since birth, the year type, and the Julian date.

This calculator was developed to be easy to use, fast, and suitable for all users, with accurate calculations that are consistent with the Umm al-Qura calendar, which is officially adopted in the Kingdom of Saudi Arabia.

How is age calculated in both the Hijri and Gregorian calendars?

The process of calculating age is based on comparing the date of birth with the current date, and then calculating the time difference between them.
When calculating age using the Gregorian calendar, the length of the Gregorian year is relied upon, which is 365 days, or 366 days in a leap year.
When calculating age using the Hijri calendar, the shorter Hijri year is used, which has an average length of 354 days, making Hijri age often longer than Gregorian age.

The tool automatically determines the correct difference between the two dates, then displays the result clearly and understandably.

Why is age in the Hijri calendar different from age in the Gregorian calendar?

The difference between the Hijri and Gregorian calendars stems from the difference in the length of the year between the two calendars.

  • The Gregorian calendar is based on the solar year.
  • The Hijri calendar is based on the lunar cycle.

Because of this difference, every 33 Gregorian years corresponds to approximately 34 Hijri years. For this reason, the Hijri age is greater by a certain number of months or years than the Gregorian age.
