1. Why should clock have 12 hours not 6 hours?

24 1 cycle 15˚ 2.5 mins*24 Day & Night
12 2 cycle 30˚ 5 mins*12 Day or Night
8 3 cycle 45˚ 7.5 mins*8 Nil
6 4 cycle 60˚ 10min*06 Morning or Noon or Evening or Night
4 6 cycle 90˚ 15min*04 Dawn or Morning or Noon or Evening
or Night or Late Night
3 8 cycle 120˚ 20 min*03 Nil
2 12 cycle 180˚ 30min*02 Nil
1 24 cycle 360˚ 60min*01 Nil
Inferences:
# 8-hour, 3-hour, 2-hour & 1-hour clock is deleted because can’t give name to the period it
showing. But 8-hour clock can be designed for office-hours.
# 24-hour & 8-hour clock may give confusion while calculating minutes.
# 24-hour clock will move slowly, indirectly it will demotivate people of saying remaining time
is lot.
Figure 1: 24-hour clock

2. # 6-hour clock will be a best fit than 4-hour clock. Because most of people won’t awake in late
night & dawn. So nothing to highlight about 4-hour clock.
So 24-hour, 8-hour, 4-hour, 3-hour, 2-hour, 1-hour clocks are neglected.
Now, we compare 12-hour clock and 6-hour clock, by theory of relativity.
Figure 2: 12-hour clock Figure 3 : 6-hour clock
Whereas 1 full rotation 12-hour clock = 2 * full rotation of 6-hour clock.
So 6-hour clock will move faster than 12-hour clock. This will indirectly motivate people in
completion of work/job on time than 12-hour clock. It is easy to denote a period as Morning or
Noon or Evening or Night.
To differentiate Morning or Noon or Evening or Night in Clock, colors for each can be
highlighted.
(OR)
A rotating set-up can be attached with the clock setup, after completion of every 6th
hour, 12th
hour, 18th
hour, 24th
hour automatically setup will show the period.
Hence 6-hour clock is a Goodness-of-Fit.
