Daylight saving time (DST).

Do not forget to shift your life back one hour this weekend.
Some interesting facts:

The practice of DST is controversial. Adding daylight to afternoons benefits retailing, sports, and other activities that exploit sunlight after working hours, but causes problems for farming and other occupations tied to the sun.

An early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity; modern heating and cooling usage patterns can cause DST to increase electricity consumption (power companies of course have nothing to do with this law).

Hawaii and some parts of Arizona ignore this.

Each year in the U.S., the Daylight Saving Time period closes near the end of October, about a week before Election Day. The extension of Daylight Saving Time into November has been proposed as a way to encourage greater voter participation.
