Does this calculator handle leap years?
Yes. The calculation is based on the total number of days, which automatically and accurately includes any leap days (February 29th) that fall within the selected date range.

Does the order of the dates matter?
No. The calculator measures the absolute duration between the two dates, so entering the later date as the "Start Date" will produce the same result.

What does "Remaining Days" signify?
It is the number of days left over after all full 7-day weeks have been counted. For example, a 10-day period consists of 1 full week and 3 remaining days.
