The whole point of having a Spirituality Forum is so that belief systems are kept separate from factual studies, isn't it? I've been disappointed that so many Science Forum threads have been contaminated by the old arguments. As if anyone was ever persuaded to change his/her beliefs by rational arguments and marshalling of facts - but the same old trolls ju ...[text shortened]... th (a solar day) should ever have been divided into 24 hours in the first place. Why 24?
Originally posted by KewpieYes, but my friend thought that before Captain Cook you would just have 1 in the morning and 1 in the afternoon whereas he started calling 1 in the afternoon 13:00 o'clock and so on.
On further checking I found this, which seems to indicate that the 24-hour pattern came first, divided into 12 hours before noon and 12 hours after noon:
Originally posted by KewpieFirstly I like to point out that in my op I mentioned that "he was said to have discovered Australia", not that he was the first to do so.
I've been hunting through Captain Cook's Journals but everywhere the references are to the 12-hour clock, not a single reference did I find otherwise.
Captain Cook did not in fact discover Australia, that honour goes to a Dutchman in 1606 and several of his compatriots, but they saw no need to do a land-grab.

And perhaps there were mystical reasons, but the main idea behind those numbers is their large number of small whole divisors. 24 hours is easy to divide in 2, 3, 4, 6, 8 and 12 parts. If you'd divide the day into 20 hours, you'd only have 2, 4, 5 and 10 as divisors. That's more useful for counting on your fingers, but less useful for astrology and astronomy, which is why these things were (semi-) standardised in the first place.

I was told by a friend that captain James Cook ,(who is said to have discovered Australia), was the first to invent this idea. Up until then we only had two 12 hour periods to make a "day".
The 24-hour time system has been used for centuries,

There are two different things being discussed here. The origin of the concept of a day being 24 hours long is certainly ancient, there are many references to that fact. The concept of having a single 24-hour measurement in everyday use rather than one of two 12-hour measurements is much more recent, and appears to have been initiated to provide more orderl ...[text shortened]... nt used against the introduction of daylight saving time in Queensland in the 1960s and 70s.
Originally posted by menace71The truth can not be told because this is the science forum.
I remembered it has something to do with the earth's rotation but still fascinating. I have a world clock app on my phone and it's to see other places and their times. Everything is either + or - Greenwich. I use military time or 24 hour time just because it actually makes more sense.
