Countdown Timer

About this tool

Updates every second using your device's local clock. Leave the tab open and it keeps counting down, and the time remaining also shows in the browser tab's title, so you can keep an eye on it from another tab. It starts on next Christmas Day; pick any date and time to count down to a birthday, holiday, exam or launch instead. The time you choose is in your own time zone, and changes to and from summer time along the way are allowed for automatically.
