The dozenal number base (base twelve) has long been known to be superior to decimal (base ten). Here is a clock demonstrating that at every time of day!
The Dozenal Suite is a set of six apps of dozenal utilities; this clock is an addendum to the Suite, a seventh app, for Apple’s mobiles (with iOS 26 or higher).
On any timing device, the day is divided by successive powers of 12, providing metric time reckoning based on twelves rather than tens. In diurnal rime, the shorter red hand circles the clock once every day (24 hours), the longer red hand once every 1/12 day (2 hours), the shorter black hand once every 1/12 of 2 hours (10 minutes), the longer black hand once every 1/12 of 10 minutes (50 seconds). All of that's much simpler and easier than the current time reckoning, which uses a mixture of bases 10, 12, 2, and 60 for its two or three hands.
In the dozenal number base, because the number 10 is one dozen, numerals ten and eleven must be single digits. They are represented by the symbols invented long ago by Isaac Pitman: rotated 2 for ten, and rotated 3 for eleven. Those are used by the two major dozenal societies, the Dozenal Society of America and the Dozenal Society of Great Britain. In plain text with dozenal numbers, ten is designated by the letter A, and eleven by the letter B.
Users may hide the small marks around the clock's circumference and hide the fastest hand. They also choose a clock format: zero at the bottom or the top (the default). For starting the clock at 6:00 AM, zero appears at the left or the right.
