Chicago in Cook County, Illinois — The American Midwest (Great Lakes)
The Standard Time System in the United States
Adopted on this Site – October 11, 1883
The Convention was called by the nation’s railroads. Delegates were asked to develop a better and more uniform time system to govern railroad operations. Previously, time had been determined by the position of the sun, with high noon as the only existing standard of exact local time. More than 100 different local times resulted from this method.
The new plan, proposed by William F. Allen, Convention Secretary, established four equal time zones across the country, each one hour ahead of the zone to its west. All railroad clocks in each zone were to be synchronized to strike the hour simultaneously.
The Standard Time System was inaugurated on November 18, 1883. On that Sunday, known as the “Day of Two Noons,” the Allegheny Observatory at the University of Pittsburgh transmitted a telegraph signal when it was exactly noon on the 90th meridian. Railroad
Although implemented by the railroads, the Federal Government, states, and cities began to use the system almost immediately. On March 19, 1918, Congress formally acknowledged the plan by passing the Standard Time Act.
