  1. Set the time to count down from.

  4. Press F for fullscreen to show it on a projector or TV.

Frequently asked questions

How is this different from the online timer?

They run on the same engine. This page opens with the large digital display, which is easier to read from a distance; switch styles any time in Settings.

Can I count down to a date instead of a duration?

For dates, use a countdown page such as the Christmas or birthday countdown, which count down to a calendar day.
