Set a countdown timer for any duration and VClock alerts you when time is up. Perfect for cooking, workouts, study blocks, presentations and games — free, accurate and instant.
An online timer counts down from a duration you choose and alerts you when it reaches zero. Unlike an alarm clock, which fires at a specific clock time, a timer measures an interval — "twenty minutes from now" rather than "at 3:40 PM". That makes it the right tool whenever the length of time matters more than the moment it ends.
VClock's timer is built around three things people actually need: it starts instantly with one click, it stays accurate even when the tab is in the background, and the alarm is loud enough to hear from another room. There is nothing to install and no limit on use.
Jump straight to a ready-made timer page — each one starts counting the moment it loads:
The single most common use. Eggs, pasta, rice, bread proofing, roast resting time — recipes are written in minutes, and a browser timer on a tablet in the kitchen is easier to read across the room than a phone screen. Run one timer per dish and use the label-free presets so you can restart with a single tap.
Time-boxing beats open-ended studying. A 25-minute block with a hard stop creates urgency and makes it far easier to start, because you are only committing to 25 minutes rather than "an evening of revision". If you want the breaks handled automatically, use the Pomodoro timer instead.
HIIT rounds, plank holds, rest periods between sets, stretching sequences. The large display stays readable from the floor, and the countdown keeps you honest about rest intervals — most people rest far longer than they think.
Keeping a talk to its slot, running timed rounds in a workshop, or limiting a stand-up to fifteen minutes. Put the timer on a shared screen and the room self-regulates without anyone having to play referee.
Board game turns, quiz rounds, exam practice under real conditions, screen-time limits and tidy-up races. A visible countdown turns "five more minutes" into something a child can see, which cuts the argument down considerably.
| Tool | Measures | Use it when |
|---|---|---|
| Timer | Counts down from a duration | "Alert me in 20 minutes" |
| Alarm clock | Fires at a clock time | "Wake me at 7:00 AM" |
| Stopwatch | Counts up from zero | "How long did that take?" |
| Date countdown | Counts down to a date | "How long until the 25th?" |
Yes, completely. There is no sign-up, no download and no limit on how many timers you run.
Yes. VClock calculates the remaining time from the actual clock, so even if the browser throttles background tabs, the countdown stays accurate and the alarm fires at the right moment.
Yes. Press Pause at any point and the remaining time is held exactly where it was. Press Resume to continue, or Reset to start over.
You can set up to 99 hours, 59 minutes and 59 seconds — far more than most people need. For anything longer, use the date-based countdown timer.
Press the Stop button that appears when time is up. The sound stops immediately and the timer resets so you can start a new one.
Yes. VClock is fully responsive and works in mobile Chrome and Safari. Keep the screen on or the browser may suspend the page.
Yes — mute the browser tab or turn your device volume down. The display still flashes and the page title changes when time is up.
So you can see the remaining time at a glance even when you are working in another tab. The title reverts to normal when the timer stops.
Use the VClock alarm clock to ring at a specific hour instead of counting down.
