Daylight Saving Time is the practice of adjusting clock time to achieve longer evening daylight, usually in summer. Clocks are set an hour ahead in the spring, then set back an hour in the autumn. The mnemonic “Spring forward, fall back” helps those who live in Daylight Saving Time areas to remember which way to set their clocks. The term Daylight Savings Time, with an “s” added to the end of Saving, is technically incorrect, though it is in usage. Daylight Saving Time was first proposed by Benjamin Franklin, though perhaps, more in jest. The first modern idea of Daylight Saving Time was proposed in 1895 by New Zealander George Hudson. It was first used in Europe during WWI, then in the United States where it was called “fast time”. Daylight Saving Time (DST) was instituted year-round in WWII, then called “war time”. Today, 70 countries practice DST, with beginning and ending dates varying.

In Britain and the European Union, Daylight Saving Time is called British Summer Time. (BST) Non-daylight saving time is called British Winter Time (BWT). British Summer Time begins on the last Sunday in March and ends on the last Sunday of October.
