Theory — how many days are between two dates?
The difference between two dates has two valid answers, and both are used in practice. The calculator computes the calendar difference, counting days without including the end date — Monday to Wednesday is two days. The inclusive option counts both end dates, the way vacation days are counted. The tool also shows the difference in years, months and days, accounting for leap years that can shift the count by one day.
