Your age in the Islamic calendar
Because the Hijri lunar year is about eleven days shorter than the solar year, your age in Hijri years is slightly higher than in Gregorian years - by roughly one extra year every thirty-three. This tool gives your exact Hijri age and your Hijri date of birth.
How it is calculated
Your Gregorian date of birth is converted to its Hijri date using the Umm al-Qura calendar, then compared with today's Hijri date to give your age in Hijri years, months, and days. As with any Hijri date, the calculated day can differ by one from a local moon sighting.
Why it is useful
Knowing your Hijri age ties your life to the Islamic calendar - helpful for noting when a child reaches the age of religious responsibility (buloogh), and for milestones linked to the lunar months.
Two calendars, two ages
Because the lunar year is about eleven days shorter than the solar one, your Hijri age runs ahead of your Gregorian age - roughly one extra year for every thirty-three lived. The gap is more than a curiosity. Religious thresholds and practices sit on the lunar calendar, and some matters of worship traditionally count years in Hijri; knowing both numbers lets you answer such questions precisely instead of approximately. There is also a quieter gift in it: a Hijri birthday lands on a different Gregorian day each year, and finding it is a small annual reminder that the calendar of your worship is its own, running quietly beneath the civil one.
Using this tool
Enter your Gregorian date of birth and the tool converts it to its Hijri equivalent, then computes your exact Hijri age in years, months, and days, with your Gregorian age alongside for comparison, along with your upcoming Hijri birthdays and the civil dates they fall on. The conversion uses the calculated Umm al-Qura calendar, so treat results near month boundaries with the usual one-day grace. Everything runs in your browser; your date of birth is never sent anywhere.
