Some may say it isn’t and relatively speaking, they may be right. However, we sometimes get some good weather in March and that’s it for the year. An extra hour of daylight, in the evening , might make it of more use.
I feel the move from BST, to GMT, in late October is well timed but I feel the move from GMT, back to BST, could come in early March, rather than at the end of it. The worst of the cold weather (If not wet weather!!!) is usually over by March and so an extra hour of daylight, at the end of the day, is more is than one in the morning. Relative to the equinox, the move to BST, at the end of March, equates to putting the clocks back in mid September, which would be absurd.
