Tonight marks the first time in 2021 we will change our clocks, marking this shift from Greenwich Mean Time (GMT) to British Summer Time (BST). Changing the clocks is a practice which is used across the globe, starting in the USA in the 1700s and first conceived by Benjamin Franklin. The idea of daylight saving time then arrived in the UK in 1907, thanks to Coldplay singer Chris Martin’s great-great-grandfather, a builder called William Willett.
Thankfully, some hundred years later, the process of changing the clocks is a lot easier for most of us.
Almost all smartphones, computers, and other devices connected to the internet will update the time automatically.
But if you have a watch or clock that isn’t digital, don’t forget to check if you will need to manually reset the time.
Your car or oven, for example, may still show the GMT time until you change the hands yourself.

Which way do the clocks go tonight?
Tonight, at 1am, the clocks will go change by one hour, making it 2am.
The clocks will go forward, marking the beginnings of lighter evenings and the first steps towards summer.
To reverse this change, we then put our clocks back in the autumn, reverting back to Greenwich Mean Time as we close in on the winter months.
When this happens, the clock goes back from 2am to 1am on the last Sunday in October.
When the clocks go forward, we lose an hour which means you will get an hour less sleep.
This change does have its benefits, however, as it is made to move an hour of daylight from the morning to the evening, spelling brighter evenings.
When the clocks go back, we gain an hour, meaning an extra 60 minutes of snoozing in bed.
This change also means we lose an hour from the evening, so it will strat to get darker earlier in the evenings. Perfect for a cosy night in by the fire.
