Frequently Asked Questions
What is a business day?
A business day is any day when normal business operations are conducted — typically Monday through Friday, excluding public holidays. The exact days vary by country and industry.
How does the calculator handle holidays on weekends?
When a federal holiday falls on a Saturday, it's observed on Friday. When it falls on Sunday, it's observed on Monday. Our calculator accounts for these observed dates automatically.
Does "10 business days" include the start date?
No. Calculations start from the day after the start date. If you start on Monday and add 1 business day, the result is Tuesday.
How many business days are in a year?
In the US for 2026, there are 250 business days. This is 365 days minus 104 weekend days minus 11 federal holidays falling on weekdays.
What's the difference between calendar days and business days?
Calendar days include every day (Mon-Sun). Business days only count weekdays (Mon-Fri) excluding holidays. A 14-calendar-day period typically has 10 business days.
Which countries' holidays are supported?
The calculator supports official holidays for the United States (Federal), United Kingdom (Bank), Canada (Federal/Statutory), and Australia (National).
