What year were time zones created in the US?
The United States started using standard time zones on November 18, 1883.
When did The US change to standard time zones?
October 11, 1883
Why were time zones first used in 1883?
Time zones were in use decades before 1883. Iceland's started in 1837, and the U.K. started in 1847. 1883 was when the United States adopted them, and as much as this information is going to break your heart, I have to tell you anyway: we are not the center of the universe. Before time was standardized into zones, each city kept its own time. As the railroads and the telegraph made transportation and communication faster, it became more and more difficult to handle all the different times. It's confusing enough with about 40 time zones around the world; imagine when there were thousands!
