How Radio-Controlled Clocks Work - By now, you have probably seen or own a radio-controlled clock. These clocks are sold in all forms: as wall clocks, desk clocks, travel alarms, and wristwatches. They have a tremendous advantage over conventional clocks, they are always right! When working properly, radio-controlled clocks always display the correct time, down to the exact second. And you never have to adjust them. This site explains how these clocks work.
The Third Millennium - The end of the second millennium and the beginning of the third will be reached on January 1, 2001. This date is based on the now globally recognized Gregorian calendar, the initial epoch of which was established by the sixth-century scholar Dionysius Exiguus, who was compiling a table of dates of Easter. Rather than starting with the year zero, years in this calendar begin with the date January 1, 1 Anno Domini (AD). Consequently, the Third Millennium does not begin until January 1, 2001 AD.
