Clocks all across the UK went back 1 hour on Sunday morning. 

But you may ask why? Why is this in effect, and how does it help us? 

We need to establish some sort of context for this, to answer that specific question.

There are time zones all across the world, that constitute the time for each specific country, depending on its longitude and latitude. 

However, there is a global time zone that exists, UTC (GMT + 0), which is based off of the Royal Observatory in Greenwich, where it was founded.  

According to the Royal Museum of Greenwich, the clocks go back to save energy, and also to increase productivity for people in winter months. 

Throughout the recent years, there has been some disputes around it.

Some people believe that it isn’t needed anymore, due to the constant hassle of changing and amending times, which can disrupt businesses.

Even in some parts of the continental Unites States, they don’t use daylight savings time either, since each state within the US can pick whether they want to use it or not, which can cause confusion. 

Time zones in general are pretty puzzling to begin with.

For example, in between Russia and the United States, there are two islands, Little Diomede, which belongs to the United States, and Big Diomede, which belongs to Russia, that are 2.4 miles away from each other, with a bewildering 20-hour difference!

Along with Daylight Savings time, this could even further it to 21 hours! This shows that time zones are arbitrary, so some people may ask why  we even use them in the first place, let alone do a traditional change of them every few months. 

Within the UK, there has been many prepositions done to change it. There was even a bill proposed in the House of Commons, the Daylight Savings Bill 2010-12, that wanted to get rid of Daylight Savings time, that failed to pass. 

In general, Daylight Savings Time is a highly useful tool that can help us in many different ways, like productivity, which can help accelerate learning and overall bring a more positive attitude into people’s hearts and mind.
