Aired (June 9, 2024): Ever wonder why we change our clocks? Join us on an adventure to discover the world of Daylight Saving Time (DST)!

00:00The questions we're going to answer this morning have to do with time.

00:04And this is our first QOTD.

00:08This was asked by Genevieve Oredina.

00:12She's only 6 years old from Quezon Province.

00:16And her question is, if it's 7am here, or 7 in the morning here,

00:20why is it that when I talk to my mom in America, it's already 6pm?

00:25That's right, Kris. Why is that?

00:28Let's find out the answer.

00:31Tick-tock, the clock said.

00:33The time we see here is different from the time of thousands of places in the world.

00:39The Earth rotates in one axis.

00:42That's why at different times, sunlight receives different places in the world.

00:47Our world is split into 24 time zones

00:51because that's how long the rotation of our planet is in its axis.

00:56That's why there are 24 time zones because there are 24 hours in a day.

01:02In the late 1880s, a team of scientists split the world into 24 time zones.

01:08There's an hour between each time zone.

01:12In North America, Europe, and some parts of Asia,

01:16there are daylight savings where people adjust their time.

01:21They advance the time by one hour every spring or summer.

01:25And they return it to the previous autumn.

01:30It's still being discussed until now where the idea came from.

01:33It's said that farmers came up with it

01:35so that they have extra hours to plant outside.

01:39But it's not just farmers who agree with this idea.

01:43In 1907, English builder William Willett promoted daylight savings.

01:49If this is done, less gas and electricity will be used every night.

01:54It's cheap, right?

01:55Nine years later, Germany and Austria followed suit

01:58to save resources during World War I.

02:02And in the early 1900s, because of the war,

02:05other countries in Europe and America followed suit

02:08and practiced daylight savings.
