Daylight savings time

The clocks went forward an hour on Sunday morning at 2am. Those of you reading in Tanzania may well not know what I am talking about.

The UK has moved into daylight savings time, meaning that here we are now one hour ahead of Greenwich Mean Time. Why? Since the UK is far from the equator, throughout the year the times of sunrise and sunset vary. In winter the sun rises later in the morning, and earlier in the evening. In summer the sun rises early, and sets late. Twice a year we adjust our clocks, and our lives, by one hour. It doesn’t really make much sense. We get up an hour earlier now than we would have done, but it doesn’t get us any extra light.
