How are months and years calculated?

The tool shows approximate months (total days / 30.44) and approximate years (total days / 365.25). These are approximations because months have different lengths. For exact calendar months, use a specialized date library.

Does it account for leap years?

Yes. The total days calculation is based on actual timestamps, so leap years are automatically accounted for. The year approximation uses 365.25 to average the leap year effect over time.

Can I calculate my age with this tool?

Yes. Enter your birth date as the start date and today's date as the end date. The result will show your exact age in years, months, days, and total days lived.

Date Difference Calculator
