Some tasks need exactly 15 hours and 20 minutes. Instead of checking the clock again and again, let the 920 Minute Timer keep track for you. It runs right here in your browser and alerts you the moment time is up.
When a 920 Minute Timer Comes in Handy

- Long-Haul Flight: Count down a long-haul flight or a night train and see how much travel time is left.
