About business days
Business days are the days that are not part of the weekend and not a holiday. Deadlines such as “within 10 business days” usually start counting the day after the start date, which is the default here.
Questions and answers
Which days count as business days?
Monday to Friday by default. You can change the weekend to Friday and Saturday, or Sunday only, and add holidays that should not be counted.
Are the start and end dates included?
The start date is not counted and the end date is, the same convention used for deadlines (“within 5 business days”). Turn on “Include start date” to count both.
Are public holidays included automatically?
No, because holidays differ by country and region. Add the holidays that apply to you and they are kept in this browser for next time.
