Who we are
DateTools is a free resource for anyone who needs quick, reliable answers to date and time questions. We build straightforward calculators and tools that give you accurate, no-nonsense results — how many days between two dates, when is the next bank holiday, how much annual leave are you entitled to, and more.
Every tool on this site is free to use, with no sign-up, no account, and no paywall. We just want to give people the clearest possible answers to everyday date and time queries.
Why we built it
When we went looking for simple date calculators online, we found plenty of cluttered, ad-heavy sites with tools that were slow, confusing, or produced results without any explanation. Nothing that just gave a clean, straight answer quickly.
So we built our own. All our tools are built specifically for UK users — using UK bank holidays, UK employment law for leave entitlements, and UK date formatting throughout. When rules or dates change, we update immediately.
How we keep the lights on
This site is free because it’s funded by ad-supported advertising. We keep ads as unobtrusive as possible — our tools and results are never influenced by our advertising relationships, and we will never place ads in a way that interferes with the tools themselves.
