Browse durations →What Makes timer.now Different
timer.now combines a quick countdown timer with bookmarkable duration pages, shareable configurations, iframe embeds and purpose-built visual, interval, presentation and focus modes. There is nothing to install or sign up for: open the relevant page, choose the settings and press Start.
Because the timer is anchored to your device's real clock, the remaining time corrects when a delayed tab or sleeping screen resumes. Your settings - The timer's name, whether sound is on, whether it loops - Are saved in your own browser, so reloading can restore the scheduled finish. A closed or suspended browser cannot guarantee sound; see how online timer accuracy and alarms work. Nothing about the countdown is sent to our server.
How to set a timer in three steps
- Pick a duration. Tap a popular preset above, or type your own hours, minutes and seconds.
- Press Start (or the Space bar). Go full screen if you want it readable from across the room.
- Watch for the finish. The page attempts to play the selected sound and flashes at zero. Test audio first and keep the page open.
Tip: Working or studying? Try the Pomodoro timer - It runs 25-minute focus blocks and short breaks for you automatically.
Which online timer should you use?
Start with the result you need. A countdown timer runs for a fixed duration, an alarm waits for a clock time, and a stopwatch measures how long something takes.
| You want to… | Best tool | Why |
|---|---|---|
| Cook, focus or take a break for a fixed length | This countdown timer | Counts down once and alerts you at zero. |
| Get an alert at a specific clock time | The online alarm clock | Waits for a time of day instead of a duration. |
| Measure elapsed time, laps or splits | The online stopwatch | Counts up until you stop it. |
| Repeat work/rest rounds automatically | The interval timer | Moves through named phases and rounds. |
| Track several independent jobs together | The online multi-timer | Runs several named countdowns side by side. |
| Count down to a date and time | The date countdown | Shows the live time left until one exact moment. |
Share, bookmark or embed the timer you need
For a shareable duration, open a ready-made page such as a 25-minute focus timer, 10-minute break timer or one-hour timer, then copy that page's URL. A shared preset gives each person the same starting duration; it does not remotely control their timer.
Need to preserve more settings? The date countdown creates a link for an exact moment, and the interval timer creates a link for work, rest and round settings. To publish a timer on another page, use the iframe timer generator. You can also browse curated durations by seconds, minutes and hours, or compare every mode in the timer tools directory.

Online Timer FAQ
Is timer.now free to use?
Yes. Every timer is completely free, with no sign-up, no download and no limits on how many you set.
Does the timer keep running if I switch tabs?
The remaining time is based on your device clock, so it corrects itself when you return. Keep the tab open: browsers and operating systems can delay or suppress audio from a background or locked device.
Will the alarm still go off if my phone screen is locked?
It may not. The display catches up from the saved finish time when the page resumes, but many phones suspend browser audio while locked. Keep the page open and visible, and use a native alarm as backup when the alert matters.
Can I set a custom time?
Absolutely. Use the hours, minutes and seconds fields to set any duration, or jump straight to a preset from the quick-pick grid.
Does it work offline?
A timer that is already loaded can continue without a connection. Opening a page or asset that your browser has not cached may still require internet access.
Can I change or turn off the alarm sound?
Yes. Pick from several alarm sounds, set the volume, or switch to a silent finish that just flashes the screen. There is a test button so you can hear each one before you start.
How do I count down to a date instead of a length of time?
Use the countdown to a date tool, or one of the ready-made countdowns like Christmas or the New Year. Pick a moment and it counts down in live days, hours, minutes and seconds.
Are there keyboard shortcuts?
Yes. Press Space to start or pause, R to reset, and F for full screen, so you can run the timer without reaching for the mouse.
Do you show ads or track timer activity?
The site may display advertising through Google AdSense. We also use Clicky analytics to understand page views and traffic sources. Your timer names, durations and settings are not included in those page-view measurements; they stay in your browser and are not sent to our server.
Is the timer accurate?
Instead of counting ticks, which can drift when a tab is throttled, it works out a finish time from your device clock and watches for it, so the display corrects to the scheduled finish time when the browser runs the page. Audible delivery still depends on browser and device permissions.
Can I put a timer on my own website?
Yes. The embed generator creates an iframe for a duration or date countdown and lets you choose the title, theme and dimensions before copying the code.
Can I share a timer with someone else?
Yes. Share a ready-made duration page, an exact date countdown link or an interval routine link. Each browser runs its own timer; sharing a preset does not give you remote control of another person's screen.
Can I run more than one timer at once?
Yes. Open the multi-timer to run several named countdowns side by side. Each timer has its own duration and controls.
