Why 12 hour and 24 hour clocks?
12 hour clock we use in our homes.24 hour clock is used in travelling places eg:airport,train station.
Why doesn't a clock have 24 hours?
Some clocks actually do have 24 hours on them, but a 24-hour clock is used by the military, some paramilitary organizations, and in other applications (like universal standard time). Most people just use a 12-hour clock. Note that most digital watches and clocks have a selectable 12- or 24-hour time.
Where could one purchase a 24 hour clock?
A 24 hour clock may be purchased online from e-commerce retailers such as Amazon. One can also find these type of clocks in limited designs from Office Clocks, Mellennium ClockWorks, Franklin Instruments, and C Crane.
Why is there 12 numbers on the clock?
The planet Earth is 24,000 miles around (circumference) and spins at 1,000 miles per hour, so a day is 24 hours long (24,000 miles divided by 1,000miles/hour = 24 hours). Since roughly half of that time is daytime, we have our clocks with 12 hour faces. There are plenty of clocks with 24 hour faces, but most still have twelve, correctly assuming that people will be smart enough to tell daytime from nightime. Navy and submarine clocks have two numbers rings on one face - the outer ring of numbers (1-12) is for AM, and the inner ring (13-24) is for PM.
When is it better to use the 24 hour clock instead of a 12 hour clock?
A 24 hour clock is better when you are running around the clock operations. Military, Police and Fire Stations use it to avoid any confusion when talking time. Factories that run around the clock, shipping companies, and airlines use it. Answer The Aviation and Space industries use the 24 hour clock as well. It reduces confusion, especially when written or oral communications are critical

How many times does a clock chime in a 24 hour day?
It depends on the clock; None of my clocks chime even once. A clock that rings the quarter hours (like the clock in the Palace of Westminster - aka, Big Ben) would chime 96 times per 24 hours. Some clocks only chime on the hours, which would be 24 chimes/day.
Why does a time have to make 2 circles to complete a day why can't we have a 24hr watch?
There are 24-hour clocks on the wall on every military base. I have also seen 24-hour wrist-watches, although very rarely. You ought to able to find either of them for sale on the internet.
Are you wrong?
No. Even a broken clock shows the correct time twice a day. (Unless it's one of those digital clocks that show a 24 hour day... ;-)
