The hour, minute, and second hands sweep automatically below - no input needed, nothing to upload.
Analog Clock Online
This analog clock runs entirely in your browser and shows the current time using your device's own clock and time zone. There is nothing to download, install, or sign up for - the hour, minute, and second hands start sweeping the moment the page loads.
Key features
Key features of Analog Clock: the SVG face starts sweeping hour, minute, and second hands as soon as the page opens - no upload, no account, and the time matches your device clock and time zone.
- A small digital readout below the clock face shows the exact time in numbers, and it updates every second in step with the hands.
- The second hand moves smoothly instead of jumping once a second: the display recalculates the hand angles about 60 times per second and factors in milliseconds, so the sweep looks continuous rather than jerky.
When to use it
Use it as a quick visual read of the current time on a second monitor, a kiosk display, or a classroom projector - anywhere you want a clean clock face without your operating system's clock or taskbar. Bookmark the page and reopen it whenever you need it; there is nothing to configure. An old phone or a spare tablet can serve the same purpose: leave the page open full-screen and prop the device up as an always-on desk or bedside clock, and the hands keep sweeping for as long as the tab stays open and the screen stays awake. The twelve hour marks spaced around the rim keep the face readable from a few steps back, without any app to sideload.
Accuracy and time zone
The time you see is only as accurate as your computer or phone's clock settings, because the clock reads your device's own system clock and time zone rather than syncing with an external server.
Privacy and data handling
Privacy and data handling for Analog Clock: nothing on this page is uploaded or stored - no account, no tracking, and no server round-trip. Closing the tab stops the display with nothing left running in the background.
How the smooth second-hand sweep actually works
The smoothness comes from pacing every redraw to your display's own refresh rate through requestAnimationFrame, so a 60Hz monitor advances the hand about sixty times each second while a 120Hz laptop or phone panel does so twice as often. Each frame reads the device clock afresh - the current seconds plus the leftover milliseconds - before it sets the angle, so the hands cannot drift out of sync; if the browser skips a frame under load the next one simply draws the true time instead of lagging behind, and the face snaps straight to the correct time when you come back to a hidden tab rather than fast-forwarding through the seconds it missed.
| How the second hand advances | Step per update |
|---|---|
| Once-a-second tick (typical digital clock) | 6 degrees per jump |
| Smooth sweep on a 60Hz screen | about 0.1 degree per frame |
| Smooth sweep on a 120Hz screen | about 0.05 degree per frame |
The one limit worth knowing is that all this precision only ever reflects your own device's clock, so a machine set a minute fast will show a flawlessly smooth second hand that is a full minute wrong.
Frequently Asked Questions
Is this analog clock accurate?
It reads directly from your device's system clock and time zone, so it is exactly as accurate as your computer or phone's own clock settings. It does not sync with an external atomic time server.
Does it need an internet connection to keep running?
Only to load the page the first time. Once loaded, the clock keeps ticking entirely from your device's own clock and makes no further network requests.
Can I show a different time zone?
Not on this page - the display always follows the time zone your device is currently set to. To see a different zone, change your device's system time zone setting.
Does it have an alarm or chime?
No. This page is a visual clock display only; it does not include an alarm, chime, or notification feature.
