What it is
EzyClock is a free clock, countdown timer, stopwatch and world clock. There is no account, no download and no paywall. Every calculation happens on your own device — the time comes from your system clock, not from our server, and no server of ours is involved in telling you what time it is.
Why it exists
Most online clocks are built to be glanced at and closed. This one is built for the opposite: to be left running. A timer stays on screen for the length of the timer, a classroom clock stays up all lesson, a second monitor shows the time all day. That changes what matters — legibility at a distance, a face that doesn't get tiring, and a full screen mode that genuinely fills the screen rather than just hiding the browser chrome.
Decisions worth explaining
- Nothing counts ticks. Timers built by counting intervals fall behind when a browser throttles a background tab. Everything here works from wall-clock time instead, so switching tabs or locking your phone doesn't corrupt the result.
- The countdown stores a finish time, not a number being decremented, so pausing and resuming can't accumulate rounding errors.
- World clock cards say Today, Tomorrow or Yesterday. Near midnight the hour alone is misleading, and that ambiguity is what causes meetings to be booked on the wrong day.
- Full screen scales on both axes. Sizing against width alone leaves half a short screen empty; against height alone it overflows a wide one.
- Reduce motion is a real setting, not just an OS preference we happen to respect — though we respect that too.
- No framework. The whole site is plain HTML, CSS and JavaScript with no build step, which is why it loads quickly and keeps working when things are blocked.
The extras
The clock sits against a sky drawn live by your own graphics hardware — not a photograph or a video. It follows the real position of the sun through dawn, daylight, dusk and night, and needs no permission to do it. Tap the weather chip and the cloud cover starts following the actual conditions where you are.
The speaker icon opens eleven ambient soundscapes — rain, storm, fog, night, plus focus presets. Every one of those sounds is generated live in your browser with the Web Audio API. There are no audio files to download, and nothing is a recording of anything that exists.
There are also four themes and six numeral fonts, including several monospaced faces whose digits never shift width as they change. Your choices are remembered on your device.
How it is paid for
EzyClock is funded by advertising, which is why the tools can stay free with no account. Ads are deliberately kept out of the way: none above the clock, and every one of them hidden in full screen mode. What we collect and who else is involved is set out plainly on the privacy page.
Who makes it
EzyClock is built by the same people as SiriTools, a workshop of browser-based file tools — merging and splitting PDFs, converting and compressing images, making a scan searchable. It runs on the same principle as this site: the work happens inside your own tab, and the file never leaves your machine. If you came here for a timer and later need to sign a PDF or shrink a photo, that is where to look.
