Why do we have DST?


I am an early riser, at 6:15 today I looked out at the wintry scene above and across at the morning twilight.  Which was lovely, and at that time of the morning there are few folk around to appreciate it which brings me onto my blog writing today.

Why do we continue to have the clock changes for winter time when we do?  The winter solstice, when the sun is at its lowest in the sky, and the daylight is at its shortest, occurs on the 21st of December.  Some 2 months earlier on the last Sunday of October we put our clocks back to GMT, the sun then rises at 7:15 and sets at 16:45.  By the 21st of February the days are getting longer and the sun rise and set times are the same as at the time change in October.  As things are at the moment however it is still more than a month till we change the clocks again and "spring" forward to British Summer Time on the 31st of March.  By then the sun is rising at 5:53 and setting at 18:51.

Would it not make so much more sense to put the clocks forward at the end of February?  We would enjoy an extra hour of daylight in the evening, and it will still be getting light by 6:45 in the morning so that should keep the farmers and school children happy and we won't need to put the lights on for another hour.  Better for the environment and our general well being.
