But What is Daylight Saving Time?

Daylight Saving Time, also called summer time, system for uniformly advancing clocks, so as to extend daylight hours during conventional waking time in the summer months.

In countries in the Northern Hemisphere, clocks are usually set ahead one hour in late March or in April and are set back one hour in late September or in October.

The practice was first suggested in a whimsical essay by Benjamin Franklin in 1784. In 1907 an Englishman, William Willett, campaigned for setting the clock ahead by 80 minutes in four moves of 20 minutes each during April and the reverse in September.

In 1909 the British House of Commons rejected a bill to advance the clock by one hour in the spring and return to Greenwich Mean Time in the autumn.

Several countries, including Australia, Great Britain, Germany, and the United States, adopted summer Daylight Saving Time during World War I to conserve fuel by reducing the need for artificial light.
