Daylight Saving time is quite a unique phenomenon practiced all over the world in many countries. This is done to make the most use of the daylight that is available to us depending on the geography of the place. However, it is important to note that not all of the countries around the world do this as evident by the list shown above. But What is it actually? Well, this basically pertains to all of the clocks within a country being turned one hour forward in spring. And setting the clock back by an exact one hour in autumn. This is basically done to add an hour of daylight in spring and compensate for it in autumn when we already have long days
This extra hour of daylight could then be conveniently used by people to go out with their families as they will be getting free from their office and other official duties an hour ahead. And will ultimately have the time to go on and do what they want to do while the sun is still up. This idea was first proposed by George Hudson from New Zealand, who initially proposed a 2-hour time shift in clocks so that he along with his friends would have more time to go for bug hunting in the summer. A few years later, this idea was appreciated by William Willett who then proposed this in front of the Parliament as a suggestion for saving daylight time of the people of the whole wide nation
Two of the many people who supported this idea were Winston Churchill and Sir Arthur Conan Doyle. But this didn’t stop the idea from being rejected in the start by the parliament. But eventually, this idea started gaining some popularity and was first materialized by the German Government.
Now that we have discussed the basic crux of it all, lets take a look into all of the countries, which one of them do use DST and at what time of the year do they change their clocks.
