Frequently Asked Questions
What counts as a business day?
A business day is any day from Monday through Friday. Weekends (Saturday and Sunday) are excluded. This calculator does not account for public holidays, which vary by country.
How do I calculate business days between two dates?
Enter your start and end dates, then click Calculate. The result shows both total calendar days and the number of weekdays (business days) between the two dates.
Does the calculator account for holidays?
This calculator excludes weekends but does not exclude public holidays, since holidays vary by country and region. For precise business day counts, manually subtract any holidays that fall on weekdays.
What is 10 business days from today?
10 business days is typically 14 calendar days (2 weeks), assuming no holidays fall on weekdays. Enter today's date and the tool calculates the exact result.
