Calculators

Date difference calculator

Count the days, weeks, and weekdays between two dates.

Loading tool…

  1. 1 Choose the start date.
  2. 2 Choose the end date.
  3. 3 Turn on “include the end date” if the last day counts.
  4. 4 Read days, weeks, and weekdays.

How it works

Pick a start and an end date. The result is the number of days between them, the same span in weeks, and how many of those days fall on Monday to Friday. You can include the end date when a deadline is counted as a full day.

Frequently asked questions

Which direction works?

If the end is earlier than the start, the gap is still shown as a positive number of days.

Are public holidays removed?

No. Weekdays means Monday to Friday, not business days in a particular state.
