Why is it 12:56 why not 11:00?

Originally, each town set its own local time and 12:00 noon was when the sun was highest in the sky. Thus the time in each town was different. When trains started running, this became annoying in trying to develop schedules. Time zones were created to standardize time over large areas.

It's partly because of school children, when clocks go back like last week, it is lighter in the mornings making it safer for them to walk to school.  When the children go home in the afternoon, it is still light enough despite it getting darker an hour earlier.\nWhy not leave the clocks there?  It is because farmers in the summer like to have an extra hour of light in the evenings so they can get more work done.  In general people like to have light longer in the evenings, especially when sitting out in the sunshine.\n\nIt does seem odd to keep messing with the clocks - some people go into work an hour early or late because they forget to change them.  My son has a Sunday job and he was up an hour earlier than he needed to be last weekend.  I just had an extra hour in bed - it does have some uses!\n\nPersonally I don't really mind the changes - in autumn it makes it feel like Christmas is nearly here, and in spring it cheers me up because summer and long evenings are on their way.

First of all, lets just look at 12 hrs, as it will be the same for the next twelve:\n\nThe minute hand revolves around the clock at 1 rev per 60 minutes, the hour hand revolves around at 1 rev per 60•12 minutes.  Knowing that after 60 minutes the minute hand is back to where it started we can say that 2π≡0.  We want to rewrite the above relations to give us the positions as a value of time.  This can be done by assuming that t is time (in minutes) and using m=2π/60t (minute hand) and h=2π/(12•60)t (hour hand).  \nTherefore we want to solve m=h+2πk for some integer 0≤k≤10.  The reason that we don't have k go to 11 is because if you think about it, the hour and minute hand never cross during the 11th hour, they keep getting closer, but then at 12:00 (during the 12th hour) they meet.\n\nThus 2π/60t=2π/(12•60)t+2πk ==>> 12t=t+720k ==>>11t=720k ==>> t=720/11k.\n\nNow, this is the time after 12:00 (midnight or noon, I don't care they; are the same). \nThese times are:\n\n12:00 (k=0)\n1:60/11=1:05:300/11≈1:05:27.27 (k=1)\n2:10:600/11≈2:10:54.55\n3:16:240/11≈3:16:21.81\n4:21:540/11≈4:21:49.09\n5:27:180/11≈5:27:16.36\n6:32:480/11≈6:32:43.64\n7:38:120/11≈7:38:10.91\n8:43:420/11≈8:43:38.18\n9:49:60/11≈9:49:05.45\n10:54:360/11≈10:54:32.73\n\nI decided to give you the second values as fractions also, since they can't be given accurately by a terminating decimal.

World standard time, based on Greenwich Mean Time, recognizes local AM and PM notations. 12:00 noon is PM, 12:00 midnight is AM. \n\nIM is not a recognized standard of time, although the locals in Meridia may well use the term loosly if they're confused about what time it is.

10:00am to 5:00am, the confusing part doesn't come in until after 12:00pm (noon).  1:00pm is 1300, 2:00pm is 1400, etc.  Up to that point, just put a : before the last 2 digits.

at different times on the earth the sun is at different positions in the sky. When it's noon somewhere, it's midnight on the direct opposite side of the earth. If a particular time was called 12 noon to everyone it would seem silly to the people where it was midnight.

because there is only 24hours a day and its easer to put 12 then 24 numbers plus 12 is half of 24 \nand there  are some watches i know that have 24 numbers instead of 12 you can buy one if u feel better with 12numbers

The same time as it was one second ago. The only reason it would change would be if the time was like 8:21:59; one second from that would be 8:22.\n :)

I think he meant to ask why a day is divided into 24 and not 36 or 48. The actual time would be the same but there would be short intervals. A half hour would end up being an hour. Why divide a circle into 360 or an hour into 60. \n\nHour :- "a traditional unit of time, equal to 60 minutes, or 3600 seconds, or 1/24 day. The custom of dividing the daylight into 12 hours goes back at least as far as the Babylonians, who liked to divide units by 12 because groups of 12 are easily divided into halves, thirds, or fourths. Originally an hour was 1/12 of the time between sunrise and sunset, so summer hours were longer than winter hours. Later, when people wanted to express times at night, it was natural to divide the night into 12 hours as well, making 24 hours in the day. Only after the invention of mechanical clocks, around 1300, did hours became equal intervals marked by clocks. The word comes from an ancient Greek word hora which originally meant a season, especially a religious season, and hence a "defined" period of time. In the Christian church hora came to mean one of the services held at seven specific times during the day, thus establishing the word as marking subdivisions of the day."

If its 15:34 in brazil the whole worlds time should be ending with rather :34 or :04.  It's all based on Greenwich mean time (GMT) Which is the time in a place in england.  All time zones are based around this time.  For example central america is 5 hours behind GMT so if it is 5:34 in england it is 12:34am or 0:34 in Central America.  Most of the time zones are in one hour increments however there are some that are a half hour difference.\nBTW there is no such thing as 7:84 or 13:64 in any country.

The only reason you are using the arcaic am and pm system is because the english language doesn´t have a single word for day and night. For the rest of us there are 24 hours to the (day + night) so it´s 00:00 which is the first minute of the first hour in the (day + night) after while 23:59 is the last minute of the (day + night) before.

Ok this still gets me sometimes but the easiest way for me to do it is to add 12 to the time then stick on 00 on the end \n\nfor example.  2pm\nyou add 12 = 14\nadd 00 = 1400\n\nthe am hours you dont do anything to it, well you dont add 12.  \n\nso 1pm would be 1300\n2pm=1400\n3pm=1500\n4pm=1600\n5pm=1700\n6pm=1800\n7pm=1900\n8pm=2000\n9pm2100\n10pm=2200\n11pm=2300\nmidnight=2400

i live in the usa, florida to be exact. i am in school now and the clock says its 8:48.

i think its still good afternoon, because theoretically the hours from 00:00 to 11:59 is morning, whereas 12:00 onwards is the afternoon.

Probably because the server is located on the West coast...this is normally why there is a difference. The service itself doesn't really have anything that would be time specific enough to call for them to allow users to set their own time zone...

Great question.\n\nTwo reasons\n\n1. It gives a sense of precision, like telling a pal "Dude, meet me this afternoon at 4:17 at Joe's Diner" and he's like "totally, 17 minutes after, my man"\n\n2. 12 midnight is neither A.M. or P.M. and the day is ambiguous. In the US Navy, any incident occurring at midnight is always reported as occuring at 2 minutes after the hour.\n\n3. Also in the lower 48 states, this time is the same date all over the country making record-keeping easier.\n\n4. Executions are traditionally carried out in the middle of the night to draw less attention to them.
