What is a countdown timer?

A Countdown Timer is an easy-to-use, accurate online timer where you can set a duration in seconds, minutes, or hours. The timer counts down from the set time to zero and then plays an alarm sound.

Use the settings to choose a different alarm, change how long the alarm plays, or switch to a silent mode. You can also restart the timer immediately once it's finished.

Our online timer is perfect for everyday tasks—like timing how long to boil an egg, limiting screen time for kids, or keeping track of sports games.

What is the difference between a countdown timer and an online stopwatch?

A countdown timer starts from the time you set and goes down to zero, playing an alarm when it reaches the end. In contrast, an online stopwatch starts at zero and counts upward, letting you measure how long something takes.

For example, you might use a stopwatch for tracking the duration of a workout, while a countdown timer is handy for tasks that need to end at a specific time.
