Tips for when the clocks change

Let’s find out exactly what happens when the clocks change and how it can affect us. We’ll also explore the ways we can combat the effects of these annual time adjustments.

In the UK the clocks go forward one hour at 1am on the last Sunday in March (unless that’s Easter Sunday).

When the clocks are one hour ahead, it’s called British Summer Time (BST). Meaning there’s more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time).¹

When the clocks go back by one hour, the UK is on Greenwich Mean Time (GMT).² This happens at 2am on the last Sunday in October.

We get less than eight hours of sunlight during the winter solstice, which occurs just before Christmas. Meaning, if we didn’t put the clocks back, sunrise would be after 9am and sunset before 5pm.³

Have you heard of ‘equinox’? It’s an event in which a planet’s subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemisphere experience roughly equal amounts of both daytime and nighttime.⁴

The dates of when the clocks change line up roughly with the equinoxes, but with a slight bias towards keeping light evenings through September.⁵

Daylight Saving Time (DST) and Greenwich Mean Time (GMT) can affect our circadian rhythm, which is how our bodies regulate our body clock. With the sudden jolt of the clocks changing, our circadian rhythms can be thrown off. This can negatively affect mood, health, and productivity.⁶

Following a 24-hour cycle, our circadian rhythm changes are physical, mental, and behavioural. These natural processes respond primarily to light and dark, and affect most living things, including animals, plants, and microbes.⁷

Are you more likely to spring into action, or fall back to sleep?

The circadian clock will reset every 24 hours for most healthy adults.⁸
