Countdown timer clocks are available for download at websites such as CNET, Online-Stopwatch and CountdownKings. All these countdown timers are free to download.
The countdown timers available at CNET allow users to set the time in hours, minutes and seconds. When the counter reaches zero, an alarm goes off. This application supports an unlimited number of timers, and some of the events suggested for timing by the developers of the software include New Year's celebrations, pregnancies, birthdays, graduations, weddings and more. The countdown timer available for download at Online-Stopwatch does not require installation, but users need to have Adobe Flash Player installed on their machines to run the application.
