🌙 What is the Hijri Calendar?

  • Type: Lunar calendar.
  • Months: 12 months, each 29–30 days.
  • Year length: ~354 or 355 days.
  • Difference from Gregorian: About 10–11 days shorter per year.

Key Hijri months:

  • Muharram (sacred month)
  • Ramadan (fasting month)
  • Dhul-Hijjah (Hajj pilgrimage)

  Hijri Age vs Gregorian Age

Because the Hijri year is shorter, a person’s Hijri age is always greater than their Gregorian age.

  • 1 Gregorian year = 365 days
  • 1 Hijri year = 354 days
  • Difference = ~11 days

Example:

  • A person born on 1 January 2000 (Gregorian) is 25 Gregorian years old in 2025.
  • But in Hijri years:
25×365354≈25.8\frac{25 \times 365}{354} \approx 25.8

So they are nearly 26 Hijri years old.

  Formula for Hijri Age

Hijri Age=Gregorian Age×365354\text{Hijri Age} = \frac{\text{Gregorian Age} \times 365}{354}

Or more precisely, by converting the birth date into the Hijri calendar and then calculating the difference in Hijri years.
