Using the tools

Instant Free Tools is free to use for personal and commercial purposes. You don't need an account. The calculators run in your browser, and what you type is not sent to our servers.

Accuracy

We test every tool and correct mistakes we find, but results are provided as is and without warranty. Check important results against an official source, especially for legal, payroll, tax, travel or medical deadlines. Public holiday data comes from the sources listed on each page and from government calendars, and can change when a government announces a new holiday.
