Common questions
About Business Days Calculator.
How do I count business days between two dates?
Choose a start and end date, select which weekdays are weekends and decide whether to count both dates. Add holiday dates to exclude them.
Does it automatically know public holidays?
No. Holiday dates differ by country and region. Paste the specific YYYY-MM-DD dates you want excluded to keep the calculation accurate.
