Practical Uses for a 170 Hour Timer
People use a 170 hour timer for very different tasks, for example:
- Sourdough Starter: A new sourdough starter needs about 5 to 7 days of regular feeding, a perfect job for a multi-day countdown.
- Exam Countdown: See how many days are left until the exam and plan your revision backwards from the deadline.
- Fermentation: Sauerkraut, kimchi and kombucha ferment for days to weeks, and the 170 hour timer reminds you when to taste.
- Moving Day: Count down to moving day and split packing, cleaning and paperwork into manageable steps.
- Project Deadline: Visualise the time left until a deadline. 7 days and 2 hours feels very different when you see it ticking.
