Who came up with the idea on who decides If we keep doing it.

I'm also talking time zones and how they keep changing for all sorts of reasons how they're linked to complain air conditioning.

So when do the clocks change?

Let's talk about the UK first, the clock spring forward on the last Sunday in March, known British summertime It, then fall back on the last Sunday in October.

Known is Greenwich Mean Time Over in the U.

S.

So British summertime is known is daylight saving time.

That's because there's more daylight in the evening unless in the mornings.

So who came up with this crazy idea of moving the clocks forward and backwards? 00:00:57.070 --> 00:01:9.200 While many people think it was Benjamin Franklin, one of the founding fathers of the United States, he is said to come up with the idea back in 17 84 when he was working in France as the first U. 00:01:9.200 --> 00:01:9.520 S. 00:01:9.530 --> 00:01:17.850 Ambassador in a letter published to the General Perry, he jokingly said that people needed to get up earlier to benefit from more sunlight.

He said that the church bell should bring out and cannon fire way.

He also thought of people got up earlier and soar more daylight than wit.

Save on candles.

Clever mom.

Then, in 18 95 this guy called George Hudson, who was a specialist in insect biology living in New Zealand's, came up with the modern version of daylight saving.

What he wanted to do was move the clocks forward by two hours in the summer, but he was mocked on It's fair to say that idea didn't fly. 00:01:53.440 --> 00:02:5.110 And then, 10 years later, a British builder called William Will It, who was also the great great grandfather of Chris Martin from Coldplay, suggested the idea again. 00:02:5.540 --> 00:02:5.950 Mr. 00:02:5.950 --> 00:02:15.050 Willett loved to play golf, but he got very annoyed when the sun went down and his games were interrupted.

He spent his life campaigning for the clocks to be moved forward, but the UK only bought it in in 1916 a year after he died, and then many years later, Coldplay released this way they are definitely linked, but It's a fact.

Fast boards, World War War and that's when changing the clocks was realized on a grand scale.

Germany was the first day to introduce this.

That was to save cold during the war.

Many others soon followed suit thin.

In World War two, the U. 00:02:57.370 --> 00:03:7.250 S made it mandatory for the whole country to use daylight saving require. 00:03:8.240 --> 00:03:10.920 That was also to save on wartime resources.

However, now states are allowed to do what they want.

More than half the countries across the world don't do it anyway.

Most of those are around the equator because the amount of daylight they have doesn't really change from season to season.

For those who do do it, many can't even decide when is the correct time to do it anywhere.

Something having daylight saving is a good thing because it saves on energy and reduces traffic accidents.

On the flip side, though, some say it doesn't save on energy.

It causes more accidents.

When Children are going to school in the morning, it's dark, and that can make it dangerous.

Some studies have even linked it to heart attacks.

So why did we do it?

Studies suggest it's all down to the economy.

Just think about it. 00:03:56.680 --> 00:04:9.280 When it's light outside and you finish school or work, you go out to the shops, the bars, the restaurants and you spend money instead of when it's dark and you just wanna rush home, Get on the sofa, put a film on, snuggle up on, go to sleep. 00:04:9.740 --> 00:04:11.250 Let's talk time zones.

In total, there are 38 time zones, some 30 to 45 minutes apart on they've got abbreviation.

Russia has 11 time zones.

The U.

S and Canada have six standard times on Australia.

Five.

Then you have China, which is the third largest country in the world.

On DDE, only has one time zone officially known as Beijing Time.

There are parts that have their own unofficial time, but officially it's China standard time.

All year round.

No clock changes.

Every time zone is measured from the Greenwich Meridian GMT based right here in London.

When me and Phoebe, that's because the U.

S. 00:04:56.100 --> 00:05:0.430 And a lot of the shipping industry were already using GMT is a point of reference. 00:05:0.630 --> 00:05:5.750 So this big international conference on time zones decided they may as well keep it that way. 00:05:6.340 --> 00:05:9.420 GMT shares the same time is coordinated. 00:05:9.430 --> 00:05:14.150 Universal time, however, they do often get confused.

G M T is a time zone and it's used only during certain times of the year in the u K U T C is the basis for time zones worldwide.

No one uses.

It is a local time.

Have you got all that?

Now I'm gonna make it a little bit more complicated.

Times and time zones have changed over the years for many different reasons.

Until the mid 19th century, different towns and cities across the UK were using their own different time, and that was according to the sun.

But with the expansion of communications and especially the railways, we'll have to get onto one single time just to give you an exaggerated example.

Imagine if you were going on the train and you got on in one city and it is 1 p.m. You traveled for three hours, you got off on. 00:05:58.630 --> 00:06:2.450 It was still 1 p.m. Oh, my God. 00:06:3.040 --> 00:06:13.550 So the railway networks introduced a single standard time across their networks, which was mainly GMT that soon became standard for the rest of the UK.

Let's pop across upon to Brazil.

They used summer saving time since the 19 thirties to try and save on electricity.

But the country noticed that the peak electricity usage wasn't in the evenings anymore when people were turning on their lights.

It was actually going to the daytime in the middle of the afternoon when people were standing on their air con.

So they've been talking about getting rid of this changing of the books together.

No decision has been major hot back across the pond to Europe, where the European Commission surveyed four and 1/2 1,000,000 you citizens, it found most don't like.

The clock's been changed forward and backwards, so things could change there, too. 00:06:55.300 --> 00:07:1.670 North Korea change time zone altogether for political reasons, you think the country would be on the same time. 00:07:1.670 --> 00:07:5.770 Zone is the South, but North Korea used to be half on hour behind. 00:07:5.770 --> 00:07:16.820 South Korea is a stand against what it described as wicked Japanese Imperialists after it's ours, were changed to match Tokyo's when the Korean Peninsula was under Japan's role.

After talks, though between the countries, South Korea's presidency sent a tweet, saying Mr Kim was so distressed by seeing the clock's out of sync.

He changed it in 2011.

The West Bank and Gaza Strip observed different local times for a whole month because the Hamas led Gaza Strip decided to ignore the Palestinians authorities daylight saving times directives, adding to tension on creating a fair bit of confusion.

So there you have it in politics and history, some good music on, so that conditioning just to quickly sum up some of the main points because I know that was a lot of information. 00:07:59.640 --> 00:08:5.830 A lot of people believe it was Benjamin Franklin who was the first person to come up with the idea of moving the clocks forward and backwards. 00:08:6.390 --> 00:08:15.440 And not all countries move their clocks, forwards and backwards, like China on some countries in Europe as well as Brazil, might stop changing their clocks.

All together countries time zones have changed over the years, most recently North Korea, which was a political move on.

In total, there were 38 time zones.

How many can you name?

And that is just a snapshot of the world.
