This coming Sunday the clocks go back one hour, with the change coming into effect at 2.00am on Sunday 31st October 2021 GMT.
It means this year you will get an extra hour in bed to prepare for Halloween Night.
This change of the clocks gives us an extra hour of daylight in the mornings until spring when the clocks go forward to BST (British Summer Time) GMT +1 Hour when There's more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time).
