Frequently Asked Questions
What is the difference between this timer and the countdown timer?
They are essentially the same tool. Both count down from a set time to zero. Some implementations may have slightly different features or interfaces. Use whichever fits your needs.
Does the timer work when my screen is off?
The timer continues running in the browser tab even when your screen is off, as long as the tab is not closed. However, some mobile browsers may suspend background tabs. For reliable timing, keep the tab visible.
Can I set a timer for multiple hours?
Yes. The timer supports up to 99 hours, 59 minutes, 59 seconds. For durations longer than 99 hours, use the Date Difference Calculator to set a target date and time instead.
How do I get notified when the timer ends?
The timer plays a sound when it reaches zero. Make sure your device is not muted and the browser allows audio. You can also enable browser notifications for alerts even when the tab is in the background.
Can I run multiple timers simultaneously?
Open multiple browser tabs, each with its own timer. This allows you to run multiple countdowns simultaneously. Some timer apps support multiple timers in one interface, but this tool runs one timer per tab.
