    China is not on another day, they simply start their day a few hours ahead of us. This occurs because of an invention called the "International Date Line." That north-south line is west of Hawaii. The global day starts west of the date line, proceeding west across Europe and North America.

    Greenwich Mean Time" (GMT) is a term originally referring to mean solar time at the Royal Observatory, Greenwich in England. It is now often used to refer to Coordinated Universal Time (UTC) when this is viewed as a time zone, although strictly UTC is an atomic time scale which only approximates GMT in the old sense. It is also used to refer to Universal Time (UT), which is the astronomical concept that directly replaced the original GMT.
