What is online timer?

Unlike a Stopwatch, a Timer is a clock that counts down from a certain time interval. The online timer can be used to set a maximum or minimum time to perform some activity.

How does a countdown work?

It works using a unit of time (hours, minutes or seconds) starting counting with the highest number, and decreasing to the lowest number. As an example of a countdown we have the arrival of the new year, where it is common to count starting in the final 10 seconds and celebrating the turn when it reaches zero.
