About the Countdown Timer
A countdown timer shows the time remaining until an event — a launch, a deadline, a birthday or the new year. This one updates every second and works entirely in your browser.
Set any future moment and the days, hours, minutes and seconds count down live.
Frequently asked questions
Does it keep running if I switch tabs?
