It was actually first introduced by the Germans in World World One, just before the UK did it. During World War Two, the UK actually used what was called British Double Summer Time (BDST), when the clocks were ahead by an extra hour during the summer. But this didn't last for very long. Now, the UK's clocks always go back by one hour on the last Sunday in October and forward by one hour on the last Sunday in March. Moving clocks like this is now done in some countries across the world, but many still don't do this. What do people think of it? Many people have different opinions about whether we should change our clocks like this.

Others don't like it because they argue that it doesn't actually save any energy, and it can make it darker when children are going to school in the morning, which can be dangerous. They also think it is not very good for our health. to see how much you've remembered about this!
