BRITISH summer time officially ends today as the clocks will went back one hour today at 2 am
But why was this implemented and when did we begin to see a distinction between “summer time” and “winter time”?
Uniform legal time
The legal time that Britain uses now was implemented relatively recently. Up until the coming of the railways, people kept time by the sun – so Manchester, for instance, would be on a different time to London. This was known as local mean time.
However, once the use of railways became widespread and commonplace the use of local mean time began to cause significant problems.
It meant that the time at one end of a railway line often differed significantly from the other, meaning passengers were often unsure at what time their train was actually departing from their station.
As a result, rail companies began to keep London time from the 1840s and in 1847 a formal recommendation was put forward for all railway companies to adopt Greenwich mean time.
In 1880 an Act of Parliament made Greenwich mean time the standard for the whole of Great Britain. Ireland initially adopted Dublin mean time but this was changed in 1916 to Greenwich mean time
British Summer Time
In 1907 William Willett – a keen horse-rider – put forward a proposal to advance the nation’s clocks by one hour during the summer.
He was incensed by what he saw as the waste of good daylight, as very often during his early-morning summer rides he would notice that, despite the sun having been up for several hours, people were still asleep.
However, he met with much opposition and spent the rest of his life fighting to implement British Summer Time. He failed to convince Government to adopt his plan and died in 1915.
However, a year later Germany adopted the system and Britain soon followed.
By this time, the two countries were at war and it was hoped by the British government that this initiative would save fuel and money. It was rapidly passed through Parliament and the first day of British Summer Time began on 21 May 1916.
Yet this was not a permanent change. During World War II, Britain adopted Double British Summer Time, where clocks remained one hour ahead of GMT in winter and two hours ahead during the summer.
Then, in 1968 a three-year experiment – called British Standard Time – was begun where the country remained one hour ahead of GMT throughout the year.
After the end of the experiment, the Government carried out an analysis – the three-year trial had produced mixed reviews from the public and it was decided to return to the original British Summer Time.
When do clocks change?
The dates that clocks should be changed was laid out by the British Summer Time Act of 1972, which stipulated that GMT would begin on the morning of the last Sunday of October and BST on the morning of the last Sunday in March.
In 2010, the date for the beginning of BST is Sunday 28 March. GMT begins on Sunday 31 October.
To change or not to change?
Nowadays the debate surrounding British Summer Time is as strong as ever and usually grows in intensity around the time of each clock change.
Safety campaigners have recommended that British Summer time be maintained during the winter and a “double summer time” enforced during the summer months.
They point to the fact that, during the experiment of 1968-71, there were fewer recorded casualties during the evenings (although the number of casualties was higher during the darker mornings).
However, others raise concerns that children going to school in such an environment would have to make the journey in the dark at the start of the day, thereby increasing the risk of accidents during that time.
For them, the fact that the number of casualties increased during the mornings between 1968 and 1971 would support their argument that putting the clocks forward in winter is unwise and the system should be left as it currently stands.
Still others have put forward arguments for doing away with British Summer Time entirely and that the country should follow Greenwich Mean Time throughout the year.
They believe that changing the clocks twice a year creates a misconception that, by doing so, people are somehow gaining an extra hour of daylight.
In spite of these arguments, it seems that for the time being British Summer Time will remain and we will continue to change our clocks twice a year.
