🕌 Islamic Age Calculator

📖 How It Works

The Hijri (Islamic) calendar is a pure lunar calendar made up of 12 months of about 29 or 30 days each, adding up to roughly 354 days per year — about 11 days shorter than the 365-day Gregorian (solar) year. Because Islamic years are shorter, your age in Hijri years runs slightly ahead of your age in Gregorian years: a person who has lived 30 Gregorian years has completed about 31 Islamic years.

This calculator uses the standard tabular (arithmetic) Islamic calendar, which assigns leap days by a fixed 30-year cycle rather than by observing the moon. Its dates can differ by one day from official moon-sighting calendars such as the Umm al-Qura calendar used in Saudi Arabia. The age in whole Hijri years, however, is essentially unaffected by this one-day difference.

Approximate — a Gregorian year spans parts of two Hijri years.
