Planning something that takes 336 hours? The 336 Hour Timer turns that time into a clear visual countdown with a progress bar, optional alarm sound and fullscreen view for the whole room.
What Can You Do With a 336 Hour Timer?
14 days is a surprisingly flexible amount of time. Here are some ideas:
- Agile Sprint: Agile teams often work in one- or two-week sprints. Show the sprint countdown on a team screen.
- Home Brewing: Beer typically ferments for one to two weeks before bottling, and a long countdown tells you when to check gravity.
- Event Countdown: Count down to a launch, a birthday, an exam or a trip and see 14 days at a glance.
- Project Deadline: Visualise the time left until a deadline. 14 days feels very different when you see it ticking.
- Exam Countdown: See how many days are left until the exam and plan your revision backwards from the deadline.
