Daylight Saving Time ends at 2 a.m. Sunday, Nov. 2. Most Americans will turn their clocks back an hour and reap an extra hour of sleep. Some locales that don't partake of the semi-annual ritual of "Spring Ahead, Fall Back" will wake up groggy as usual.

We word wonks at Hammock are compelled to point out that it is not "Savings" time, but "Saving" time. (We're not sure where the "s" came from, though we suspect it's the same shadowy source for such misnomers as "JC Penney's" and "Kroger's." One wonders if Sears, Walgreens and Starbucks decided not to fight this peculiar trend and stuck the "s" on themselves. How Wal-Mart has avoided the problem is a mystery. But I digress.)

According to the US Naval Observatory, this year was the 90th anniversary of Congress' establishing standard time zones as well as daylight saving time. The latter didn't go over well, and was repealed in 1919, (the same year that the 18th Amendment creating Prohibition was ratified; it was a big year for social engineering).

Daylight time was drafted into wartime service in World War II, then became a local matter after the war ended. The Uniform Time Act of 1966 standardized beginning and ending dates, though localities could opt out. The energy crisis of the mid-1970s expanded the effective dates for daylight time, and our current crunch led to The Energy Policy Act of 2005 that starts daylight time on the second Sunday in March and ends it on the first Sunday in November.

So don't forget to set all your clocks - and be sure to tell your family: Once I forgot to announce I had changed the clocks and someone else did, too. The extra sleep was nice, though.
