Hijri Age Calculator Online – Calculate Your Islamic (Hijri) Age in Years, Months & Days
Want to know how old you are according to the Islamic (Hijri) calendar? Our Hijri Age Calculator Online helps you find your exact Islamic age instantly in Hijri years, months, and days. Whether you wish to celebrate your Islamic birthday, check your age for Hajj, or compare your lunar and solar ages — this free online tool gives you precise and reliable results in seconds.
What Is a Hijri Age Calculator?
The Hijri Age Calculator is an online tool that calculates your age based on the Islamic lunar calendar, instead of the standard Gregorian (solar) calendar. Since the Hijri calendar follows the moon’s cycle, each month has either 29 or 30 days. As a result, one Hijri year equals approximately 354 or 355 days — making it about 10 to 11 days shorter than a Gregorian year.
Our Hijri Age Calculator instantly converts your Gregorian date of birth into its equivalent Hijri date, giving you your exact age in Islamic years, months, and days.
How Does the Hijri Age Calculator Work?
Just like a regular age calculator, it subtracts your birth date from today’s date — but in this case, it uses the Hijri lunar system. Here’s the formula:
Hijri Age = Current Hijri Date − Hijri Date of Birth
Because the lunar year is shorter, your Islamic age may be slightly older than your Gregorian age. For example:
Example: If your Gregorian birth date is 1 January 2000, your Hijri birth date is approximately 24 Ramadan 1420. As of 18 October 2025, your Hijri age would be 26 years and 5 months — about one year older than your Gregorian age.

Understanding the Hijri Calendar
The Hijri calendar (also known as the Islamic lunar calendar) began in 622 CE — the year of Prophet Muhammad ﷺ’s migration (Hijrah) from Makkah to Madinah. It consists of 12 lunar months, including Muharram, Safar, Rabi al-Awwal, Ramadan, and Dhul-Hijjah. Since it follows the moon’s cycle, the start of each month depends on the sighting of the new crescent moon.
This calendar is essential in Islam, as it determines the dates of key events such as Ramadan, Eid al-Fitr, Eid al-Adha, and Hajj. Using the Hijri Age Calculator helps you understand your position in this sacred calendar.
Gregorian vs Hijri Age Difference
The main difference between the two calendars lies in the number of days per year. A Gregorian year has 365 days, while a Hijri year has only 354 days. This means your Hijri age is usually 1 to 2 years older than your Gregorian age, depending on your birth date. This difference is useful when tracking Islamic anniversaries or religious milestones.
Example Calculations
Example 1: DOB – 5 May 1995 (Gregorian) → 5 Dhu al-Hijjah 1415 (Hijri). Age on 18 October 2025 ≈ 30 Hijri years, 3 months, 10 days.
Example 2: DOB – 1 March 2010 (Gregorian) → 15 Safar 1431 (Hijri). Age on 18 October 2025 ≈ 16 Hijri years, 1 month, 2 days.
