Date Calculator counts the exact number of days between two dates — also shown as years, months and days, as weeks, and as working days (Monday to Friday). Switch to “Add or subtract” to find the date that is a number of days, weeks, months, years or working days before or after another date. Leap years and month lengths are handled automatically.
