Have you ever wondered why do we change the clocks twice a year? Why do we “spring” our clocks forward in March and rewind them back in November?
The purpose of changing our clocks, or better called Daylight Saving Time (DST), is, as the name implies, to make better use of the daylight and conserve energy.
The time zone we use from November till March is called Standard time. By setting our clocks one hour later during the Summer time, we automatically set sunrise and sunset one hour later so we can have more daylight. (the article continues after the ad)
One of the weird things about this change is that the GMT (Greenwich Mean Time) stays the same. Therefore, in summer time, even though Greenwich is in London, London is actually GMT+1.
