Date Difference Calculator

Count the days, weeks, months and working days between two dates.

How many days are between two dates?

A date difference calculator counts the calendar days between two dates and breaks the result down into years, months, weeks and working days.

Results

  • Total days and weeks
  • Working days (Monday to Friday)
  • Years, months and days
  • Hours and minutes

Include the end date?

By default the count is exclusive: from 1 January to 2 January is 1 day. Tick "Include the end date" when both days count, such as for hotel nights booked or a holiday period (1–2 January = 2 days).

Working days exclude Saturdays and Sundays but not public holidays, which differ by country. To find a date a number of days away, use Add or Subtract Days from a Date.
