Frequently Asked Questions

How accurate is this age calculator?

Our calculator provides 100% accurate age calculations by accounting for leap years and the exact number of days in each month. It's more precise than simple year subtraction.

Can I calculate age differences between two people?

Yes, simply calculate each person's age as of today or a specific date, then subtract the results. We'll be adding a direct age difference calculator in a future update.

Why does my age show one day less than expected?

This occurs when calculating age at midnight before your birth time. Our calculator counts full 24-hour periods, so your exact age anniversary occurs at your birth time, not calendar midnight.
