This page is for anything that is broken, wrong or missing: a tool that will not start, a bank holiday date that does not match the official list, a calculation that produces a result you can show to be incorrect, or a tool you expected to find here and did not.

What makes a report easy to act on

For anything that is not working, the browser and device matter more than anything else you can tell us — "Safari on an iPhone", "Chrome on a Windows laptop", "Firefox on a Mac". Alarms, timers and stopwatches lean heavily on behaviour that differs between browsers, so that one detail often identifies the problem on its own. Add the address of the exact page and what you expected to happen instead, and there is usually enough to work with.

For a date or holiday correction, please include the date, the nation it applies to — England and Wales, Scotland or Northern Ireland — and, if you can, a link to the official source you are working from. Bank holiday dates are set separately for each nation and the differences are exactly where mistakes creep in.

Before reporting an alarm that did not ring

By a wide margin the most common report is that an alarm failed to sound, and in almost every case the cause is one of a handful of things: the tab was closed or the browser was quit, the device went to sleep or locked its screen, the volume was down, the tab was muted, or do not disturb was switched on. None of these can be overridden by a web page. If none of them applies, the report is genuinely useful and worth sending.

How to get in touch

A contact address for the operator of this site will be published on this page. Until it appears here, there is no other channel to use, and no address elsewhere on the site should be treated as one. The site is run by a single operator rather than a support team, so replies may not be quick.
