Why do we change our clocks twice per year?
Thanks for asking. Spring forward, fall back goes the saying.
That's right! Today saw the clocks go back an hour, meaning it gets dark earlier all of a sudden and winter is on the way.
Now if there's one day, or rather two days of the year, when you don't want to schedule any important appointments, it's on a day when the clock changes.
Forgetting the time change is something that's happened to all of us at least once.
Changing our clocks is so ingrained into our culture that we never really call it into question.
But it has actually become a subject of debate in recent years, with some people even saying we should do away with the whole idea.
Who first came up with the idea then?
A British -born New Zealand entomologist called George Hudson was first to suggest daylight saving times in the modern era, towards the end of the 19th century.
But in the UK it was builder William Willett who campaigned fervently to have it implemented in the early 1900s.
He printed pamphlets entitled The Waste of Daylight and managed to get the idea debated in the House of Commons for the first time.
During the First World War a need to conserve coal led to daylight savings being brought in.
The Summertime Act was passed in May 1916, although William Willett himself sadly wasn't around to see it.
He had died a year prior from flu.
What's the point of it all?
Let's take a moment to briefly revisit high school geography.
On the equator you get roughly 12 hours of day and night the whole year round.
Whereas the further north or south you go away from the equator, the more unbalanced things get.
By adjusting the clocks it means we get an extra hour's daylight after our working day in the spring and summer.
The typical arguments in favour of daylight savings are that having lighter mornings in the summer means we reduce unnecessary energy consumption and even traffic accidents.
Logic also dictates that people will get up and out earlier when it's light causing them to be more active.
Well that makes sense, why is it a subject of debate then?
Critics have said that claims about energy savings and reduced traffic accidents are overstated.
Most of them see daylight savings as meddlesome more than anything else, but some have suggested it could even be dangerous.
Certain studies have shown that there's an increased number of heart attacks and strokes in the week following a time change.
After all, the practice is an unnatural interference with our body clocks, which as you may recall from our recent episode on circadian rhythms, control all of our bodily functions.
Back in 2018 the European Commission passed a proposal to end daylight savings time.
That was due to happen in 2021, but then the Covid pandemic came along and it became of secondary importance.
It also proved a matter of quite some debate within the EU.
Northern countries like Denmark and Finland want to stick to winter time, while their southern counterparts want to remain on summer time.
Question about the matter back in March, then Prime Minister Boris Johnson said it was unlikely the UK would follow the EU in ending daylight savings.
