It's that time of year again where we all run around like headless chickens, asking if we have an extra hour in bed or an hour less because of the clocks changing.
While most digital clocks change automatically now, don't get caught out this year.
There's nothing worse than being an hour late on Monday - or *shudder* an hour EARLY.
Here's everything you need to know about the clocks changing...
Why do the clocks change?
We're changing back from Daylight Savings Time to Greenwich Mean Time (GMT). It was introduced in 1916 to make the winter evenings brighter and to save on candles in the summer mornings.
When are they going back?
They're going back on Sunday (the 28th of October) at 2am, so at 10am it will actually be 9am.
However, if you use your phone as an alarm that will automatically update, so don't go back to sleep thinking you have another hour. You will have already had it during the night.
Do you need to do anything?
As mentioned above, phones and digital clocks will update automatically, but you will need to change microwaves and analogue clocks.
