Daylight Savings Time didn’t become a big deal in the US until WWII, when Americans “sprung forward” in February 1942 and didn’t “fall back” until September 1945. If changing time wasn’t confusing enough, there wasn’t a set date for changing the clocks and made in hard to coordinate transportation and broadcasting schedules. Massive confusion abounded until 1966 when Congress passed the Uniform Time Act, which brought the time change for everyone on the same day.
