Frequently asked questions
Does this count the start and end date?
The calculator includes the start date and excludes the end date by default (standard business day convention), but you can verify the count in the detailed output.
Can I add my country's public holidays?
Yes — paste your holiday dates (YYYY-MM-DD format, one per line) in the Public Holidays field and they will be excluded from the working day count.
Does it work for any year?
Yes — enter any date range across multiple years and the calculator handles them all.
Is this tool free?
Yes, completely free with no account required.
Can I exclude only Saturdays and keep Sundays?
Yes — the Saturday and Sunday exclusion checkboxes are independent.
Does it show the result month by month?
Yes — after calculating, you see a breakdown of working days per month in the range.
