SUMMARY

The discussion addresses the historical and practical reasons behind the division of time into 12 months and 24 hours. It highlights that the current system, including the use of 60 seconds in a minute, stems from ancient civilizations' preferences for easily divisible numbers. The Roman and Babylonian influences on the calendar are noted, particularly their affinity for multiples of 6. Additionally, the concept of decimal time has been proposed but has not been widely adopted.

PREREQUISITES
  • Understanding of historical timekeeping systems
  • Familiarity with the concept of decimal time
  • Knowledge of ancient civilizations' contributions to modern calendars
  • Basic arithmetic related to divisibility and fractions
NEXT STEPS
  • Research the history of the Roman calendar and its evolution
  • Explore the concept of decimal time and its proposals
  • Investigate the significance of the number 12 in various cultures
  • Learn about the practical applications of time divisions in navigation and other fields
USEFUL FOR

Historians, educators, and anyone interested in the cultural and mathematical foundations of timekeeping systems.

This is as I would describe it beyond what has become the norm that dictates how we define our lives in This world. Why does there have to be 12 months in a year and 2 12 hour divisions between night and day instead of some other length of duration such as 14 or 13?

Your question is not really appropriate to this section which applies to scientific theories of elementary particles beyond the Standard Model. Your question should rather be posted under Philosophy or General Discussion.

But to answer your question, firstly there's no reason it couldn't be otherwise and there have been in past "decimalization" movements suggesting alternatives especially 100 "seconds" to a "minute" etc, and 10 months to a year. See http://en.wikipedia.org/wiki/Decimal_time" in wikipedia and check out the related topics.

You're question would be better answered if you did a little history research and contemplation as to why we have the systems we currently use.

One common reason for using divisions of 12, 24, and 60 parts is it is easily divided into small increments, i.e. halves, thirds, quarters, and sixths, etc.
A 24 hour day for example is useful in dividing watches on ships into 6 four hour watches, http://www.boatsafe.com/nauticalknowhow/shipbee.htm" . That'd be tougher with say a 17 "hour" day.

i'm guessing 'the ancients' had a month for each zodiac and by the time we reched the roman calendar, the months shifted a bit
 
The romans (and ancient babylonians, I think?) had some obsession with multiples of 6. That's really all there is to it.
