About this countdown timer
This timer runs entirely in your browser using accurate timestamp-based counting, so it won't drift even if the tab is in the background for a while. When it reaches zero, you'll see an on-screen alert and hear a repeating tone.
Useful for time-boxing meetings, presentations, or breaks — especially when coordinating with a team across time zones using the overlap tool.
