About alarm-clock.org
alarm-clock.org is a free, browser-based alarm clock, timer, stopwatch, world clock and collection of live event countdowns — no app, no account, no sign-up.
Why alarm-clock.org exists
Most of the time, a quick timer or a countdown to something you're looking forward to shouldn't require installing an app, creating an account, or handing over an email address. alarm-clock.org exists to be the fast, no-friction option: open a page, and the tool is already working.
Fast, browser-based tools
Every tool on this site runs entirely in your browser tab. Pages are built to load quickly and work the moment they appear, with no separate download and nothing to configure first. That same browser-based approach has real limits — see browser timing limitations for what it means for background tabs, mobile devices, and anything where missing a moment really matters.
What we're committed to
- Speed — pages load fast and tools work immediately, with no unnecessary delay between opening a page and using it.
- Accuracy — event dates, tide predictions, sunrise/sunset times and other data are sourced and computed as precisely as the underlying source allows, and corrected quickly when they're not.
- Transparency — where information comes from an outside source (NOAA tide predictions, public event dates), that source is stated on the page rather than left unclear.
- Accessibility — pages are built to work with a keyboard, a screen reader, and a range of devices and connection speeds, not just a mouse on a fast desktop.
- Continuous improvement — the site is actively maintained: dates get refreshed, broken links get fixed, and new tools get added over time.
Independent operation
alarm-clock.org is independently run and isn't affiliated with any device maker, operating system, or other clock or countdown product. It's supported by advertising and the occasional affiliate link, which keeps every tool free to use with no sign-up.
Errors and corrections
If something on the site is wrong — a date, a time, a data point — we want to know. Every content page links to a way to report it, and reports go to a person, not a queue nobody reads.
- Wrong or outdated event date: use the Wrong date? link at the bottom of the page in question.
- Anything else that looks off, or abusive content: use the Report abuse link at the bottom of any page — it's pre-filled with the page you're reporting from.
- An idea for something we should add: use the Share an idea box near the bottom of most pages.
