Age Difference Calculator
Enter two dates of birth to see the exact difference between them in years, months and days.
How It Works
The calculator treats the earlier date of birth as the reference point and the later one as the target date, then applies the same calendar-accurate age calculation used by the Age Calculator.
Example
Comparing a birth date of 10 March 1990 with one of 22 July 1994 shows a gap of 4 years, 4 months and 12 days.

- Can I use this to compare siblings' ages?
- Yes, this is a common use — enter each sibling's date of birth to see the precise gap between them.
