What is the Days Between Dates Calculator?

Counts the time between two dates in days, weeks and days, years-months-days and weekdays (Monday to Friday). Choose whether to include the end date, or jump ahead 30, 90 or 365 days.

How it works

How to use the Days Between Dates Calculator

3 simple steps. No experience needed.

What can you use it for?

  • Count down the days to a trip or event.
  • Work out a notice period or deadline.
  • Count working days for a project.

How the count works

Without the end date, the count is the number of midnights between the two dates — from Monday to Friday is 4 days. Including the end date adds one, which is how you'd count the days of a trip.

Dates are compared as calendar days, so daylight saving changes don't add or remove an hour from the result.

FAQ

Frequently asked questions

Should I include the end date?

Include it when both the first and last day count, like the days of a holiday or a hotel stay. Leave it off for “how many days until” questions.

Are public holidays excluded from weekdays?

No — holidays differ by country and region, so only weekends are removed.
