So, you've just woken up and somehow you feel more refreshed than usual.
The reason for that is the clocks have gone back, despite happening every year people are still often caught out by this.
The clocks going back means that the UK will be moving from British Summer Time (BST) to Greenwich Mean Time (GMT).

Changes to the clocks took place at 1am this Sunday when most people were probably tucked in bed.
However, if you were still up at this time you may have noticed that once your phone's clock hit 2am it instantly jumped back an hour.
While electronic devices such as mobile phones, laptops and computers usually automatically adjust to the time change, manual clocks require you to put a bit of care in and change them yourself.

Because of the time adjustment, expect to have an extra hour in the day which means you can have an extra lie-in in the mornings and a bit more time to get everything done during the day.

Why do the clocks change?
Benjamin Franklin first had the idea to change the clocks in autumn back in 1784.
He argued that people would benefit from extra daylight if they got out of bed an hour earlier.
But the idea wasn't introduced to the UK until 1916, when the first Daylight Saving Bill was brought in.
It's quite a while until the clocks go forward again - March 27 where we'll go back to BST.
