The gap between the two ages is not an error: the lunar year is eleven days shorter than the solar one, so 33 Gregorian years amount to about 34 Hijri years.

How do I calculate my age in Hijri years?
Your Hijri age comes from converting your Gregorian birth date into the Hijri calendar, then measuring the gap to today’s Hijri date. Because the lunar year is about eleven days shorter, your Hijri age is always the larger of the two — by roughly one year for every 33 years lived.
Why is my Hijri age higher than my Gregorian age?
A Hijri year is twelve lunar months, about 354 days. A Gregorian year is 365 days. That eleven-day annual gap accumulates, so someone who has lived 33 Gregorian years has completed about 34 Hijri years.
Is this calculation exact?
It uses the tabular Hijri calendar adopted in official and computational systems. Where the month begins with a physical moon sighting, the date may differ by one day.
