Analog Dozenal Clock

Analog Dozenal Clock

I first posted this at Dozensonline after writing about my afterthoughts on dozenal clocks.

Analog clocks are visual aids, so having too many hands clog up the image. We don’t need to see more than two hands. Only in our standard inefficient 24x60x60 clock system do we need that many. In fact, with a pure dozenal clock, a single hand is enough.

If we divide the day in twelfths, we can see the entire day on a single revolution of the hand. Our current system has us learn between 12 hour and 24 hour clocks. That is redundant and done away with in dozenal clock. The dozenal clock closely matches the position of the sun like a sundial, without extra effort from us to convert back and forth from convoluted hour and minute cycles.

A day can be divided into quarters. We call them after-midnight, morning, after-noon, and evening. Then these quarter-days can be further divided into threes: early, mid, and late. Thus the dozenal clock immediately tells us the part of day:

  1. Early after-midnight
  2. Mid after-midnight
  3. Late after-midnight
  4. Early morning
  5. Mid morning
  6. Late morning
  7. Early after-noon
  8. Mid after-noon
  9. Late after-noon
  10. Early evening
  11. Mid evening
  12. Late evening

The next division by twelve gives us an equivalent of ten minutes on our current clock system. This provides us both the hour and minute values with a single digit in a dozenal clock, without cumbersome and wasteful conversion to base 60.

Because twelve is such an easily dividable base, a large clock can subdivide into sheeks (one-twelfth of a day) and karafs (one-twelfth of sheek). Thus a single hand is good enough to tell the time of day that is as exact as the nearest ten-minute in our current clock. For smaller clocks or for more precision, a second hand can be employed to provide us the accuracy to the nearest fenet (one-twelfth of karaf, about 50 seconds in our current time system.) But even comparing two-handed clocks, the dozenal clock also tells us the part of the day and is more precise (nearest 50-second versus nearest 60-second.)
