Can I exclude more than five holidays?

The calculator allows up to five holiday fields; additional holidays would need to be accounted for manually or by adjusting the date range.

What if my work week does not follow Monday through Friday?

The tool defaults to a five-day work week; users in regions with different standard work days may need to manually adjust the result or input dates accordingly.

Does the tool account for leap years or month lengths automatically?

Yes, the calculator processes the full date range provided, including any leap years or varying month lengths, and subtracts the appropriate weekend days.

Is the result affected if I swap the start and end dates?

The calculator typically expects a start date that precedes the end date; reversing them may produce an error or zero result, as the tool is designed for forward date ranges.
