How this is calculated
Business days = Every day from start to end, inclusive, excluding Saturdays and Sundays
Example
July 1 to July 31, 2026 (31 calendar days): 23 business days, with 8 weekend days excluded.
Step-by-step guide
- Enter the start and end dates.
- Read the business day count, along with total calendar days and weekend days excluded.
Common mistakes
Assuming this excludes public holidays automatically - it only excludes weekends. Subtract holidays manually if they fall within your range.
Forgetting this counts both the start and end date if they're weekdays - it's an inclusive count, not exclusive.
Frequently asked questions
Does this exclude public holidays?
No - holidays vary by country and even by industry, so this counts only Monday through Friday. Subtract any known holidays from the result manually.
Is the start date included in the count?
Yes - if the start date falls on a weekday, it counts as one of the business days, along with the end date if it's also a weekday.
What is this commonly used for?
Estimating shipping and delivery windows, calculating project deadlines, and figuring out contractual notice periods that specify business days rather than calendar days.
