Does this calculator handle leap years?
Yes. The calculations are based on the popular `date-fns` library, which correctly accounts for leap years to provide an accurate duration.
Is the end date included in the calculation?
The calculation measures the full periods (years, months, days) between the start and end dates. The end date itself is the endpoint and is not counted as a full day in the duration.
