Frequently Asked Questions
Adding business days means counting forward (or backward) from a start date, skipping Saturday and Sunday and any selected public holidays. For example, adding 5 business days to a Monday gives you the following Monday — because the weekend is not counted.
No — counting starts from the next business day after the start date. This is the standard used in banking, legal filings, and commercial contracts. So "5 business days from Monday" ends on the following Monday, not that Friday.
If the start date is a weekend or public holiday, the calculator automatically shifts to the next (or previous, when going back) working day before counting begins. A notice in the result will flag when this adjustment has been made.
Many legal and commercial documents state timeframes in business days — net 30 business days for invoice payment, 5 business days for delivery SLAs, 1 month notice periods. Using calendar days gives the wrong deadline, especially over bank holidays. This tool gives you the precise date.
