From wikipedia:\n"Daylight saving time (also called DST) is the North American term for a system intended to "save" daylight (the British observe summer time, and likewise the Europeans). The official time is adjusted forward, (usually) one hour from its official standard time, remaining that way for the duration of the spring and summer months. This is intended to provide a better match between the hours of daylight and the active hours of work and school."\n\nIn my own wordings, it's adjusting time in summer/winter so you won't be going to school/work when it's dark, or waking up at 6am and the sun is too high in the sky.\nCountries usually adjust the time to make the change between summer/winter in sunrise/sunset easier on people.

Day consist of 24 hrs. First 12 hrs AM and next 12 hrs PM. Our watch shows only 12 hrs.

I dont know.  How did the english get the world to go along with it?  Also why not have 12 hours of light and 12 hours of dark.  Instead they do 6am is sunrise.  Why not 1am sunrise and 1pm sunset.

Because a 24 hour period is a day, it's simple to refer to the days of the week as Monday, Tuesday etc.  The first part of the name does have meaning of some sort, though I'm not sure what, I think some of this goes back to the Ancient Roman era.

I see your problem\n\nWe conventionally call it 12pm, but I think I understand why you're asking the question: how can noon or 12 midday be "<post> meridien" if midday <is> the meridien?\n\nSure, it is "post meridien" as soon as the second hand passes the 12, but at the exact instant of midday it can be neither am nor pm.\n\nSimilarly, midnight is both exactly 12 hours after midday (post meridien) and 12 hours before midday (ante meridien)....

"“AM” stands for the Latin phrase Ante Meridiem —which means “before noon”—and “PM” stands for Post Meridiem : “after noon.” Although digital clocks routinely label noon “12:00 PM” you should avoid this expression not only because it is incorrect, but because many people will imagine you are talking about midnight instead. The same goes for “12:00 AM.” Just say or write “noon” or “midnight” when you mean those precise times. \n\nIt is now rare to see periods placed after these abbreviations: “A.M.” , but in formal writing it is still preferable to capitalize them, though the lower-case “am” and “pm” are now so popular they are not likely to get you into trouble. \n\nOccasionally computer programs encourage you to write “AM” and “PM” without a space before them, but others will misread your data if you omit the space. The nonstandard habit of omitting the space is spreading rapidly, and should be avoided in formal writing. \n"

AM= After Midnight\n\nThis handy NASA site about latitude and longitude says P.M. in a time means "post meridian." On a map, the horizontal lines that are parallel to the equator are called lines of latitude. The vertical lines that go from pole to pole are the lines of longitude. A longitude line is also called a meridian. That comes from the Latin words for "middle" and "day." Everywhere along the same meridian experiences noon at the same time, and meridian used to mean "noon." So times before the meridian are "ante meridian," and times after are called "post meridian." These phrases are abbreviated as A.M. and P.M.
