How it's calculated
business_days = count of days where weekday ∈ {Mon…Fri} between start and end (inclusive)
Common questions
Are holidays excluded?
No — only weekends are removed. Subtract the number of public holidays in your region that fall on weekdays for a true working-day count.
Is the end date included?
Yes. The range is inclusive of both endpoints, so start = end gives a count of 1 day.
