Business Days Calculator
Calculate business days between dates or add business days to a date.
Timeline
This tool calculates the number of working days (excluding weekends, and optionally holidays) between two dates - useful for project planning, calculating delivery estimates, or figuring out deadlines that only count business days rather than calendar days.
Frequently asked questions
Basic calculation excludes weekends (Saturday/Sunday); if holiday exclusion is supported, check the tool's options to specify relevant holidays for your region, since these vary by country.
The standard Monday-Friday work week is the default assumption in most calculators, though some countries/regions have different weekend days (like Friday-Saturday in parts of the Middle East) - check the tool's settings if your context differs from the standard assumption.
Most business day calculators support both: finding the number of business days between two dates, or projecting forward N business days from a given start date to find an end date.
