British Summer Time is right around the corner

Britons will soon rejoice as lighter evenings are on the horizon, with the clocks set to go forward shortly.

Clocks will go forward by one hour as the UK enters Daylight Saving Time.


The change takes place on the last Sunday of March at 1am.

This year, the time will go forward by one hour on March 30, which is Mother’s Day.

Signaling the beginning of British Summer Time, at 1am, the clocks will go forward by an hour.

This means that, for the next eight months, the sunrise and sunset will happen an hour later resulting in extra daylight in the warmer months.

Sadly, this does mean that Britons will miss out on an hour in bed.

Whilst the clocks will officially go back at 1am, smartphones and other devices will change automatically in the early hours of the morning.

The Palace of Westminster Clockmakers will also complete their intricate operation to alter the Great Clock of Westminster inside Big Ben.

However, Britons will need to adjust clocks and watches to make sure they do not get their timings wrong going forward.

The clocks will stay the same until October 26, when Britain will revert to Greenwich Mean Time.

A popular way to remember which way the clocks will be adjusted is: “Spring forward, fall back.”

Daylight Saving Time was introduced during World War One to help people maximise sunlight throughout the year.

It was first adopted by Germany in 1916, in an attempt to help conserve energy - fewer electric lights and less heating was needed in the lighter evenings.

Soon after, other European countries took up the practice. In the UK, it was called British Summer Time.

In World War Two, the UK even had British Double Summer Time, which meant the clocks were changed by two hours.

It is believed that the ancient Romans also followed a similar practice in order to use their time efficiently during the day.
