Why is the Hijri year 11 days shorter than the Gregorian year?
The Hijri year is lunar: twelve lunar months of 29 or 30 days each, totalling about 354 days. The Gregorian year is solar, at 365 days. The eleven-day gap is why Islamic occasions drift backwards through the Gregorian seasons.
Is this conversion exact?
It uses the tabular Hijri calendar adopted in official and computational use. In countries where the month begins with the physical sighting of the crescent, the date may differ by one day.
How old am I in Hijri years?
Your Hijri age is higher than your Gregorian age because the lunar year is shorter — roughly 34 Hijri years for every 33 Gregorian ones. For your exact Hijri age and your next lunar birthday, use the Mawlidi calculator on the home page.
