Age Difference Calculator
Enter two birth dates to see the exact gap between them.
How the age gap is worked out
Enter two birth dates. The difference is counted from the earlier date to the later one in whole years, then months, then days, so it reads naturally: for example, 3 years, 2 months and 5 days.
Use it for siblings, couples, parents and children, or historical figures. The total number of days is exact, including leap days, so it also works for comparing any two dates.
