They save it so that there will be some light for the people that have to go to school and to work etc. in the mornings.
Daylight saving time (DST), also known as summer time, is a conventional local time adopted by many countries of the world on a seasonal basis. Most commonly DST is obtained by adjusting the official local time forward, by one hour, for the spring, summer, and early autumn periods.
DST is mostly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness across the seasons in those regions.
Governments often promote it as an energy conservation measure, on the grounds that it allows more effective use of natural sunlight resource in summer time. Since there is less darkness in the "waking day", there is less use of electric lights. Some opponents reject this argument (see below, Criticism).
Europeans commonly refer to the system as "summer time": Irish Summer Time, British Summer Time, and European Summer Time. This is reflected in the time zones' names as well, e.g., Central European Time (CET) becomes Central European Summer Time (CEST).
The word "summer" in this context includes most of spring after the spring equinox and a large part of autumn. Likewise, the word "winter" here includes part of autumn and a few weeks in spring. This varies by time zone, of course, and can change over time as well.
Have a nice day!

Saving daylight was first mentioned in 1784 by Benjamin Franklin in a letter to the editors of the Journal of Paris, wherein he urged Parisians to get up earlier in order to use sunlight, thus saving wax by not burning candles at night. He did not mention Daylight Saving Time—he did not propose that clock time be changed. As the satirical article was humorous, it is extremely clear Franklin did not seriously propose that the French adopt it. The mere suggestion that a tax be levied on those who have their shades drawn during daylight hours, or simply that people should get up and go to bed earlier, is ludicrous.
DST (changing time) was first proposed by William Willett in "Waste of Daylight", published in 1907, but he was unable to get the British government to adopt it, despite considerable lobbying.
The idea of DST was first put into practice by the German government during the First World War, between April 30, 1916 and October 1, 1916. Shortly afterward, the United Kingdom followed suit, first adopting it between May 21 and October 1, 1916. On June 17, 1917, Newfoundland became the first North American jurisdiction to adopt DST with the passing of the Daylight Saving Act of 1917. On March 19, 1918, the U.S. Congress formally established several time zones, which had been in use by railroads and most cities since 1883; at the same time they made DST official, effective March 31, for the remainder of World War I. It was observed for seven months in 1918 and 1919. The law, however, proved so unpopular, mostly because it obliged people to rise and go to bed earlier than had become customary since the advent of electricity, that it was repealed in 1919, when Congress overrode President Woodrow Wilson's veto of the repeal.
