when was daylight savings invented in the us
Daylight saving time Starting on April 30, 1916, the German Empire and its World War I ally Austria-Hungary introduced DST (German: Sommerzeit) as a way to conserve coal during wartime. Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the next year, and the United States adopted daylight saving in 1918.
Central Time Zone Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.
12-hour clock The American Heritage Dictionary of the English Language states "By convention, 12 AM denotes midnight and 12 PM denotes noon. Because of the potential for confusion, it is advisable to use 12 noon and 12 midnight."[22]
Veterans Day Congress amended the bill on June 1, 1954, replacing "Armistice" with "Veterans," and it has been known as Veterans Day since.[6][7]
