Frequently asked questions

Are there any usage caps on the Business Days Calculator?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the tool.
Does anything I enter leave my computer?
No. The Business Days Calculator runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
Who is the Business Days Calculator for?
In practice it gets used for three things: calculating an SLA or delivery window. Working out billable days on a contract. Planning a project schedule around holidays. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Can I rely on this for exact work?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
