About the Deadline Calculator

Project timelines are usually quoted in business days, since work doesn't happen over weekends. This calculator finds the actual calendar date a deadline lands on by counting only Monday through Friday.

How it works: Starting from the given start date, the calculator steps forward one calendar day at a time, counting a business day only when the day is not a Saturday or Sunday, until it reaches the requested count.

Note this simplified version does not exclude public holidays — only weekends. Useful for quoting turnaround times, shipping estimates and project due dates.
