How to use the days-between-dates calculator

  1. Choose the start date.
  2. Choose the end date.
  3. The calculator automatically shows the number of days, weeks and workdays (Monday–Friday) between the dates.

How the days are calculated

The calculator subtracts the from-date from the to-date, and counts the number of whole days between them:

Number of days = To date − From date

Workdays are counted by going through each day in the period and excluding Saturdays and Sundays. Note that the calculator does not account for public holidays, which vary from year to year.

Note: The workday count only excludes Saturdays and Sundays — not public holidays. The actual number of working days may therefore be somewhat lower.

Frequently asked questions

Does the calculator count the start and end date?

The calculator shows the number of whole days between the two dates (the difference). If you want to count calendar days including both dates, add one day to the result.

Why doesn't it account for public holidays?

Public holidays vary by country and some follow movable dates (like Easter), changing from year to year. This calculator only excludes fixed Saturdays and Sundays for a general workday estimate.
