Frequently asked questions
- Does this account for leap years?
- Yes — the calculation is based on real calendar dates, so leap years are handled automatically.
- Can I calculate age as of a future or past date instead of today?
- Right now this tool always calculates age as of today. For a specific date range, try the Date Calculator instead.
- Why do the years, months, and days look slightly different from other calculators?
- Different tools round differently. This one always shows a whole number of years, then the remaining months and days.
