March 19 is best known for the Standard Time Act of 1918, the law that gave the United States official time zones and its first national daylight saving time. The date also saw Nevada legalize casino gambling in 1931 and the Sydney Harbour Bridge open in 1932.
The big story: Congress Sets the Nation’s Clocks (1918)
Before 1918, no federal law set the nation’s time zones. On March 19, 1918, with the United States fighting in World War I, President Woodrow Wilson signed the Standard Time Act. Its official title promised “to save daylight and to provide standard time.” The law wrote five zones into federal law: eastern, central, mountain, Pacific and Alaska. It also told Americans to move their clocks ahead one hour on the last Sunday in March and back on the last Sunday in October. The idea was that an extra hour of evening light would stretch the workday and save fuel for the war. The first national spring-forward came at 2 a.m. on March 31, 1918. The daylight saving part did not last. Congress repealed it in 1919, after just two summers. The time zones stayed, and so did the argument over changing the clocks.
