Frequently asked questions
Are the tools free?
Yes. Every tool is free to use, with no account and nothing to install.
Which date do the tools use as today?
Your device's date. Pages are prepared for US Eastern Time and switch to your own day automatically when it is different.
Do you store what I enter?
No. Dates you type into calculators stay in your browser, and personal details such as birth dates are only kept in the page address after the # sign, which is never sent to our server.
