Daylight saving time - Wikipedia, the free encyclopedia

Daylight saving time - Wikipedia, the free encyclopedia: "Daylight saving time (DST), also known as summer time in British English, is the convention of advancing clocks so that evenings have more daylight and mornings have less. Typically clocks are adjusted forward one hour in late winter or early spring and are adjusted backward in autumn. Details vary by location and change occasionally; see When it starts and stops below."
