Get ready to lose an hour of sleep from tonight on.
The clocks are moving forward tonight, as daylight saving time begins ahead of the longer Summer evenings.
Clocks will go forward an hour overnight tonight, at 1am on the 31st of March.
While most devices connected to the internet such as your phone or your PC will move forward automatically, your alarm clock or grandfather clock may need a bit of a tweak tonight.
Clocks will move back an hour again at the end of October.
