A simple hours, minutes and seconds countdown timer can be used by typing in the desired amount of time and pressing "Set" or "Start," according to Online-Stopwatch. The online timer will usually flash on the screen when it reaches zero or start a beeping alarm. Users should make sure that their computer's sound is turned up enough to hear the beeping timer.
A more involved online timer takes a little more effort, but may allow users to create a header message and set the time for a date months into the future, notes Time and Date. Using one of these timers is still fairly intuitive.
