Using the years difference calculator
This calculator provides a comprehensive breakdown of the time between any two dates:

The main result shows years, months, and days. The secondary line shows total days, total months, and decimal years.
Understanding the calculation
The calculator counts every day starting from the first date but does not include the last date in its calculation. This method ensures that the calculation is precise, whether the dates span multiple months or years (or even leap years).
Accounting for leap years
The calculator automatically includes leap years in the calculation. This feature makes sure the calculation is accurate across any span that includes February 29 (including if it happens, you know, more than once!).
