The term "meridian" means "midday" or noon.The original definition of the Prime Meridian placed it at the "center" of the day, or noon, when the Sun could be determined as "directly overhead" at some point along the 0° meridian. This meant that midnight, the division between days, was at the 180° meridian, or "International Date Line", when it was noon in Greenwich. At that point, all points on the globe are marking the same calendar day.Because the Sun arrives overhead earlier east of the Prime Meridian, the time there is already after noon that day. Points west of the Prime Meridian will have their noon later that day, so they are "earlier" in the day.The terms "ante meridiem" (A.M. before noon) and "post meridiem" (P.M. after noon) follow the same convention. When it is afternoon at the Prime Meridian, a new day begins at the Date Line and "moves west" with the passing hours. Except at midnight, the Date Line will indicate a "day later" to its west than to its east.
The abbreviation for "before noon" is "AM." It is the abbreviation for the Latin phrase ante meridian which means "before the high point (of the sun)"Similarly, "PM" is the abbreviation for the Latin post meridian, meaning "after the high point"
