why the number on the clock is 1 - 12?

Answer 1

My clock as numbers 1 - 24? Yours must be a smaller clock.

Answer 2

because the earlier clocks were based on day and night.though the day and night are not exactly 12 hours each at all places at all times this is how the 24 hours came to be divided into 2 twelve hours and hence the 12 hour clock

Answer 3

"The hour was originally defined in ancient civilizations (including those of Egypt, Sumer, India and China) as either one twelfth of the time between sunrise and sunset or one twenty-fourth of a full day. In either case the division reflected the widespread use of a duodecimal numbering system. The importance of 12 has been attributed to the number of lunar cycles in a year, and also to the fact that humans have 12 finger bones (phalanges) on one hand (3 on each of 4 fingers). (It is possible to count to 12 with your thumb touching each finger bone in turn.) There is also a widespread tendency to make analogies among sets of data (12 months, 12 zodiacal signs, 12 hours, a dozen)."
