Don't forget to put your clocks forward one hour on the last weekend in March.

The clocks change in March and October each year as part of Daylight Savings Time (DST)

When do the clocks change in March 2015?

This clocks will go forward one hour at 1am on Sunday, March 29.

So if you've got to get up early on the Sunday, make sure you remember!

Why do the clocks change?

The idea of changing the time was first put forward by astronomer George Vernon Hudson in 1895.

He wanted to bring the working hours of the day into the daylight period, and utilise lighter evenings.

But it wasn't until World War One that DST was implemented — Germany led the way in April 1916 in a bid to save fuel for the war effort, and Britain adopted DST in the May of that year.

Some groups, including farmers, prefer lighter mornings and argue for Greenwich Mean Time to be used all year round.

However some campaigners want to keep DST throughout the winter months and put the clocks forward another hour in summer, meaning evening longer light in the evenings.

But the idea has failed in the House of Commons as parts of northern Scotland and Northern Ireland would see sunrise as late as 10am - meaning some children would be forced to walk to school in the dark.
