Daylight Saving Time
Daylight Saving Time ends this Sunday - November 1st - at 2:00 am. For many of us that means turning clocks back one hour. Why do we do this?
Daylight saving originated with the Standard Time Act of 1918, P.L. 65-106. This law was repealed the next year, but was made law again with the Uniform Time Act of 1966. The law was codified as 15 U.S. Code ยง260 et seq.
To see how this law has changed over time, visit the law library and we'll show you how to use HeinOnline, or our print versions of the U.S. Code and U.S. Statutes at Large.
