Frequently asked questions
What about half-day holidays?
Treat them as either full holidays (which remove a day) or as a full working day with reduced hours. The calculator does not support fractional days.
Why does the calendar day count differ from the workday count?
Weekends and the listed holidays do not count as workdays but do count in the total calendar span.
