Over the years the image of the clock has been abstracted and stylized to a point where a long and a short line inside a circle, or even inside four dots on the ordinals, can be instantaneously recognized as a clock. This is perfectly fine if you already know how to read the analog clock but it makes no sense to use such a design as a teaching aid.

As a teaching device, you need to make sure all the information that has been abstracted away has been put back.

That is the basic principle of the ccClock

  • The minute hand points at the minute dial
  • All the minutes are listed removing the need to know the 5 or 15 math table
  • The Clockwise direction is emphasized with arrows and text orientation.
  • The two per day rotation of the hour hand is described using a concentric spiral
  • The progression of day into night is indicated by recognizable icons of the rising and setting sun and moon
  • The written format is described in the traditional dial digits
  • The spoken form is described in speech balloons

what do you mean 'no one says that'?

If the time is 9:04, I don't say "four after nine" or "four past nine", I say "nine oh four". Dag-nabbit! kids these days.
