Why do I get 1 day between today and tomorrow?

By default the counter measures elapsed time, so consecutive dates differ by one day. Enable "include end date" to count both endpoints — useful for durations like hotel stays or prescriptions.

Does it handle leap years?

Yes. The calculation uses real calendar dates, so February 29 and different month lengths are automatically accounted for.
