About this 55-minute timer
A one-click 55-minute countdown, most often used for meetings with a hard stop, a long work block, or checking long bakes. It runs in your browser and rings when it reaches zero.
Fifty-five minutes
Fifty-five minutes is an hour with a five-minute buffer. It's the 'speedy meeting' length some calendar tools offer so back-to-back meetings don't overlap, and a good timer when you have a hard stop on the hour.
