Full Years
Calculates the total number of full, completed years.
→
2
Full Months
Identifies remaining full months within the leftover period.
→
3
Remaining Days
Counts the final number of days to get the precise duration.

Frequently Asked Questions

How does the "Add Years" function handle Feb 29th?

If you add years to a Feb 29th and the target year is not a leap year, the Years Calculator will intelligently adjust the date to Feb 28th of that year. This is the standard and correct way to handle this scenario.

Is the end date included in the "Years Between" calculation?

The calculation measures the full duration up to the beginning of the end date. For instance, the duration from Jan 1st to Jan 2nd is exactly 1 day. The end date itself is the boundary, not part of the counted duration.

Can I calculate the duration for dates in the past?

Yes. The Years Calculator works for both past and future dates. Simply ensure your Start Date is earlier than your End Date for a positive duration result. If the start date is after the end date, the calculator will notify you.
