Clocks will go FORWARD one hour overnight tonight.
The 'Summertime' changeover will happen at 1am - when time leaps forward to 2am.
Unfortunately it will give you one hour less in bed for Easter Sunday morning.
If you have a smartphone or any device that connects to the internet, your time will automatically change - but watch out if you're depending on a more traditional type of alarm to get you up! and don't get caught out.
The clocks will eventually return to wintertime on Sunday 27th of October.
