How it works

Count working days in three steps

1. Pick two dates

Enter the first and last day of the period. Decide whether the end date itself should count.

2. Set your week

Monday to Friday is the default. Switch the working week and add public holidays if they apply to you.

3. Read the total

See business days, calendar days, weekend days and working hours, updated as you type.

FAQ

Common questions

Does the calculator include the start and end dates?

The start date is always counted if it is a working day. The end date is counted too, unless you untick "Count the end date". Untick it when you want the number of working days until a date rather than through it.

Are public holidays excluded automatically?

No. Holidays differ by country, region and company, so you add your own under "More options". Enter each date as YYYY-MM-DD, one per line, and any that fall on a working day are taken off the total.

What if my working week is not Monday to Friday?

Choose Monday to Saturday, or Sunday to Thursday for countries where the weekend is Friday and Saturday, under "More options".

How many business days are in a year?

With a Monday to Friday week there are 260 or 261 weekdays in a year, depending on which day it starts. Subtract your public holidays to get the working total, which is usually between 250 and 253.

How are working hours worked out?

Working hours assume a standard 8-hour day, so they are simply the number of business days multiplied by 8.
