This is the tool to reach for when a contract says "10 business days", when you are estimating an SLA or delivery window, or when you need to know how many working days remain before a filing deadline. If your organisation works a non-standard week - for example Sunday to Thursday - the Working Days Calculator lets you choose exactly which days count.
