Daylight saving time (DST), also known as summer time, is a widely used system of adjusting the official local time forward, usually by one hour from its official standard time, for the spring, summer, and early autumn periods. The term Daylight savings time, although commonly used, is technically incorrect.
DST is most commonly used in temperate regions, due to the considerable variation in the amount of daylight versus darkness across the seasons in those regions.
Governments often tout 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).

It is not worldwide. The US and Canada are the only countries I know of that have it.

Japan and India are the only countries that do not observe some form of daylight saving.

Many countries in the world have it, all European countries, Australia (I think) and I was in Egypt when they had it too. I suspect it is to do with the distance from the equator, the closer you get the less likely the country would be to do it.

It's not even countrywide in the USA. Indiana and Arizona do not recognize daylight savings time.

Well, there's some places in the US that don't have it. But I'm sure most places do.
