UK clocks go forward at the weekend!
Britain’s clocks go forward an hour at 0100 GMT (0200 British Summer Time) on Sunday 27 March, in line with most European countries.
So if you’re in Europe and phoning elsewhere in the world on Sunday morning, bear in mind that people will be an hour earlier than they were relative to you, and don’t drag them out of bed early by mistake!
Likewise, if you’re phoning from elsewhere in the world to Europe, remember that they’ll be an hour further ahead than they were.
