Frequently asked questions

Does the Best Time to Post Calculator cost anything?
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.
Is what I paste into the Best Time to Post Calculator stored?
No. The Best Time to Post 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.
When would I actually need the Best Time to Post Calculator?
In practice it gets used for three things: setting a posting schedule for a new account. Adjusting for an audience in another time zone. Choosing a launch time for an important post. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything to watch out for?
Published "best times" are averages across millions of accounts. Your own analytics beat any general chart — use these windows as a starting hypothesis and then test against your own data.
How precise is the result?
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.
