About Days Between Dates Calculator

The difference between two dates is the number of calendar days from the first to the second. By default the end date is not counted, so Monday to Friday is 4 days; tick the option to include it. The calculator also breaks the span into years, months, and days by calendar subtraction, and into weeks, hours, and minutes. The order of the dates does not matter, and times of day are ignored.

Also known as: Date Difference Calculator, Date/Time Difference.
