Daylight saving time (DST) in the UK is where we put the clocks forward in spring, setting them back again in the autumn. The time in between is known as British Summer Time (BST). UK standard time is known as Greenwich Mean Time, or GMT.
The origins of the practice in Britain date back to the early 1900s, mainly as a way to make the most of daylight hours. Beforehand people would sleep through the light hours of the early morning.
In Europe all countries shift their clocks at once. The shift to British Summer Time is made at 01:00 GMT on the last Sunday in March. So the time will immediately become 02:00 BST. The shift back to GMT is made at 02:00 BST, when the time will become 01:00 GMT.
In the spring you lose an hour and in the autumn you gain the hour back. An easy way to remember this is “Spring forward, fall back.” (Fall as in autumn).
Next change: Sunday 29th March 2015, 01:00 GMT
At 2 o clock on the Sunday morning you will need to put all your clocks back by one hour. Or do it before you go to bed or when you first get up. Many digital items, such as phones and computers may automatically adjust their time.
Here are the dates and times for daylight saving changes for next year:
Sunday 29th March 01:00 GMT until Sunday 25th October 02:00 BST
In 2010 the Daylight Saving Bill was introduced to Parliament with a look to extend daylight saving all year round. The United Kingdom would effectively run on GMT+1 for the whole year. Supporters of the bill state that if made law it would reduced road traffic deaths, especially during the winter months. Some opponents from Scotland claim that the change would adversely affect them due to their north westerly position.
