Daylight Saving Time in WWI
It is the practice of setting the clocks forward one hour from standard time during the summer months, and back again in the fall, in order to make better use of natural daylight and save energy costs during WWI
Hawaii and Arizona (except for the Navajo nation) do not observe it
In America, it first became official on March 19, 1918 when the Standard Time Act was signed into law
It was only in effect for about a year and a half before it was repealed due to wars end
The loss of natural daylight and the expense of energy costs came up again during WWII. In February 1942 congress implemented a law insisting a national daylight saving time.
Because it was first made to help the war, it was nicknamed "war time"
The time zones were even known as that: "eastern war time, pacific war time, etc."
Farmers opposed because workers worked less as they came and went according to the clock
For farmers it was the sun-not the hands of the clock-that dictated their schedules
When the war ended in 1945 the law once again repealed so individual states could establish their own standard time
For the next two decades their were no set rules for daylight saving time, which caused a lot of confusion for the transportation and broadcast industries
In 1966 congress passed the uniform time act that set a national standard time that permanently superseded local times
This established daylight saving time from the last Sunday in April to the last Sunday in October
