When do the clocks go back in 2022?

The clocks go back one day before Halloween this year, on Sunday, October 30 2022. When the clocks go back, the UK is on Greenwich Mean Time (GMT).

Does it happen across the UK?

The clocks go back every year on the last Sunday of October in the UK and go forward forward on the last Sunday in March. Globally, in the likes of North America, Daylight Savings Times (DST) starts on the second Sunday in March clocks go back on the first Sunday in November.

Daylight Saving Time begins every year in parts of Australia on the first Sunday of October.

Why do we change them?

The clocks are moved forward an hour and back so we can make use of the best natural light as the earth orbit the sun. The countries that are further from the equator get more hours of darkness from the clock changing.

It was invented by a New Zealand entomologist named George Vincent Hudson in 1895. During the First World War, Germany and Austria introduced clock changing in a bid to save on coal consumption. The Allies followed suit.

It is believed adding extra daylight hours into the working day saves on energy.

Will I need to update my mobile phone?

Mobile phones should automatically update with the new times depending on the model you own. Apple iPhones, iPad and Macs update automatically, but it is advised you check you have ‘set automatically’ turned on in your ‘date and time’ settings.

If you have an Android phone, it is also advised that you check you have 'automatic updates' set to your phone.
