Use the built-in Clock app’s Timer page to create separate, named countdowns, then start, pause, reset, and reuse each one independently. This works in the Clock app on Windows 11 and Windows 10. On either version, you can close the Clock window or lock the PC after starting a timer; the alert can still appear as long as Windows is awake and notifications and sound are allowed. Windows 10 reached end of support on October 14, 2025, but its included Clock timer feature continues to work on existing installations.

A Windows Clock app shows three timers—Oven, Rice, and Study break—with an Oven timer alert on the desktop. Before you create timers​

A timer counts down from a duration you choose, such as 5 minutes for tea, 25 minutes for focused work, or 45 minutes for laundry. It is different from an alarm, which is intended for a fixed time of day.

For the most dependable result:

  • Use a distinct name for each timer, especially when several may finish close together. Examples: Pasta, Study break, Oven, or Meeting wrap-up.
  • Confirm that your speakers, headphones, or Bluetooth audio device are connected and audible.
  • Keep the PC awake if the timer must alert you while you are away from the screen.
  • Test a short timer before trusting the setup for cooking, medication, a meeting deadline, or another time-sensitive task.
  • Update the Clock app through Microsoft Store if your Timer page looks substantially different from the steps below. The controls can move slightly as the app is updated.

The Clock app includes preset timers. These are useful for common durations, but creating named timers is a better approach when you need to manage several separate tasks.

Create your first named countdown timer​

  1. Open Start.
  2. Type Clock in Search, then select Clock from the results.
  3. In Windows 11, select Timer from the left navigation pane. If the navigation pane is collapsed, select the navigation button near the upper-left corner first.
    In Windows 10, select Timer from the app’s navigation area.
  4. Review the preset timer cards already shown on the page. You can use one of these directly, but do not overwrite a useful preset if you want to keep it unchanged for later.
  5. Select the Add new timer button. It is normally shown with a plus (+) icon.
  6. Set the countdown duration. Enter the required hours, minutes, and seconds. For example:
    • Set 00:25:00 for a 25-minute study period.
    • Set 00:10:00 for a short break.
    • Set 01:00:00 for an hour-long task.
  7. Enter a meaningful name in the timer name field. The name helps identify the correct alert when more than one timer is running.
  8. Select Save.

The new timer appears on the Timer page as its own card. At this point it is saved but not running. Its displayed time should match the duration you entered, and its name should identify the task.

Create and run multiple timers​

Each timer card is independent. You do not need to wait for one countdown to finish before creating or starting another.

  1. Repeat the Add new timer process for every separate task you need to track.
  2. Give each timer a unique name. Avoid names such as Timer 1 and Timer 2 if the tasks have different purposes. Descriptive names make finished notifications much easier to recognize.
  3. On the card for the first timer, select Start.
  4. On the card for the next timer, select Start when that task begins.
  5. Continue starting timers individually as needed.

For example, you could run these three timers at the same time:

  • Oven — 20 minutes
  • Rice — 15 minutes
  • Kitchen cleanup — 10 minutes

Because each card has its own controls, you can begin the cleanup timer later without changing the oven or rice countdowns.

While timers run, leave the Clock app open if you want to monitor remaining time visually. You can also switch to another app, minimize Clock, or lock the device. The timer continues to count down, but Windows must remain awake for an on-screen notification to be delivered reliably.

Pause, resume, and reset a timer​

A timer card changes its available controls after it starts.

  1. To temporarily stop a running countdown, select Pause on that timer’s card.
    The time remaining should stop changing. Other timers continue normally.
  2. To continue the same countdown, select Start or Resume on the paused timer card.
    The timer should continue from the remaining time rather than returning to the original duration.
  3. To abandon the current countdown and return the timer to its saved starting duration, select Reset. The Reset control is normally represented by a circular arrow.
  4. Before resetting a running timer, pause it first if the app requires that control sequence.

Reset is the key to reusing a timer. For example, a 25-minute focus timer can be reset after each work session rather than created again from scratch. The name and original duration remain available for the next session.

Important: Resetting a timer discards its current remaining time and restores the original duration. If you need to preserve the remaining time, use Pause instead.

Respond when a timer reaches zero​

When a countdown reaches zero, Clock should provide an alert using Windows notifications and sound. The exact presentation can vary with your Windows notification settings and whether the screen is locked.

  1. When the timer alert appears, read the timer name to identify the completed task.
  2. Select Dismiss to clear the alert.
  3. Return to Clock > Timer if you want to review or reuse the completed timer.
  4. Select Reset on the timer card to restore its original duration.
  5. Select Start when you are ready to use that timer again.

If you miss the initial banner, open the notification area to check for recent alerts:

  • Windows 11: select the clock or notification bell on the taskbar, or press Windows key + N.
  • Windows 10: select the notification icon on the taskbar, or press Windows key + A.

Do not assume a dismissed notification automatically prepares the timer for another round. Open the Timer page and reset the timer before starting it again.

Make timer alerts noticeable​

A timer is useful only if you notice it. Configure Windows notifications and power behavior before depending on multiple timers during a busy work session or while you are away from the desk.

Check Clock notification permissions​

On Windows 11:

  1. Open Start > Settings > System > Notifications.
  2. Make sure the main Notifications switch is turned On.
  3. Find Clock under Notifications from apps and other senders.
  4. Select Clock.
  5. Turn on:
    • Show notification banners
    • Show notifications in notification center
    • Play a sound when a notification arrives

On Windows 10:

  1. Open Start > Settings > System > Notifications & actions.
  2. Ensure Get notifications from apps and other senders is turned on.
  3. Under Get notifications from these senders, select Clock.
  4. Turn on the options to show banners, show notifications in Action Center, and play sounds.

A banner provides the immediate on-screen alert. Notification Center or Action Center provides a second chance to find an alert you did not see when it first appeared.

Check Do Not Disturb or Focus Assist​

Windows can silence ordinary application notifications during a focus period, at scheduled times, while presenting, while gaming, or when a full-screen app is in use. Alarms have special treatment in some Focus Assist configurations, but do not rely on a countdown timer bypassing notification suppression without testing it first.

On Windows 11:

  1. Open Start > Settings > System > Notifications.
  2. Check whether Do not disturb is enabled.
  3. Review automatic rules if alerts seem to disappear at certain times or while using a particular activity.

On Windows 10:

  1. Open Start > Settings > System > Focus assist.
  2. Check whether Priority only, Alarms only, or an automatic rule is active.
  3. Review automatic rules for gaming, duplicated displays, full-screen apps, and scheduled hours.

If you intentionally use Focus or Do Not Disturb, start a one-minute test timer to confirm whether its banner and sound still arrive under your preferred settings.

Add a visual alert as a backup​

If you may not hear the timer, Windows can flash part or all of the screen when an audio notification arrives.

On Windows 11:

  1. Open Start > Settings > Accessibility > Audio.
  2. Expand Flash my screen during audio notifications.
  3. Choose the visual alert that best suits your workflow.

On Windows 10:

  1. Open Start > Settings > Ease of Access > Audio.
  2. Under Show audio alerts visually, choose the preferred option.

This is especially useful when working with headphones, in a noisy room, or when you need a visual cue instead of a sound.

Keep the PC awake for critical timers​

Clock timers can run while the app is closed or the device is locked. However, if Windows puts the device to sleep, notification delivery may not be visible or audible until the PC wakes.

Warning: Extending sleep time increases power use and can reduce battery runtime. On a laptop, use this only for a timer that genuinely needs an alert while you are away. Restore your usual sleep settings afterward.

On Windows 11:

  1. Open Start > Settings > System > Power & battery.
  2. Expand Screen and sleep.
  3. Adjust the sleep timing so the PC stays awake for the duration of the timer when plugged in or on battery, as appropriate.
  4. Start a short test timer, lock the PC, and wait for the alert.

On Windows 10:

  1. Open Start > Settings > System > Power & sleep.
  2. Adjust the sleep setting for the power state you are using.
  3. Test with a short timer while the device is locked.

To roll back this change, return to the same Settings page after the task and restore the previous sleep timeout.

Troubleshoot timers that do not alert or do not behave as expected​

The timer is counting down, but there is no sound​

  • Check the Windows volume control and confirm the device is not muted.
  • Confirm the correct output device is selected, particularly after connecting Bluetooth headphones, a docking station, or an external monitor.
  • Go to Clock’s notification settings and turn on Play a sound when a notification arrives.
  • Test with a one-minute timer while the Clock app is open. If it works only while Clock is open, review sleep settings.

No banner appears when the timer finishes​

  • Go to Settings > System > Notifications in Windows 11, or Settings > System > Notifications & actions in Windows 10.
  • Confirm notifications are enabled globally and for Clock specifically.
  • Turn on Show notification banners and the option to retain notifications in Notification Center or Action Center.
  • Check Do Not Disturb or Focus Assist and its automatic rules.
  • Open the notification area after the test to see whether the alert arrived silently rather than as a banner.

The timer did not alert while the PC was locked​

A locked PC can still show timer alerts, but the device needs to remain awake. Check the Screen and sleep or Power & sleep settings, then test a short timer with the device locked but awake. If you close the lid of a laptop, its configured lid action may put it to sleep; use a plugged-in, awake device for a critical countdown.

You accidentally reset a timer​

Reset returns a timer to its original saved duration and removes the current remaining time. There is no rollback for the discarded countdown position. Re-enter the remaining duration manually if you know it, then save or start the corrected timer.

You cannot tell which timer finished​

Edit or recreate the timers with clear, distinct names. Include both the task and context where useful, such as Upstairs laundry, Front burner, or Client call wrap-up. For recurring work, retain a small set of named timers and reset them between uses rather than making unnamed duplicates.
