About
Countdown counts down to any future date and time — a launch, a deadline, a wedding — displaying days, hours, minutes, and seconds, and the current countdown state is shareable via a URL so you can send a live countdown link to someone else. Unlike Timer, which counts down a duration you type, Countdown is anchored to a specific calendar date. Runs entirely in your browser.
