Episode Overview

This episode tackles the question: "Why do we have Daylight Saving Time?" Molly and her kid co-host, Ava, explore the science, history, and effects of shifting our clocks twice a year. They mix playful banter, clear explanations, and several fun segments for curious kids and adults alike. Listeners learn not only why Daylight Saving Time (DST) exists, but also how it affects our bodies, why it isn’t actually about saving daylight, and where it came from.

Key Discussion Points & Insights

1. What is Daylight Saving Time? (03:48–06:12)

• Definition: Moving clocks one hour forward in the spring, so evenings have more daylight, and one hour back in the fall.

• Ava and Molly joke about what hour they would skip or repeat if they could control time, with Ava wanting to skip a long bus ride and repeat an hour before school to get more sleep.
  “I would skip four to five because that’s my bus ride and it’s really long and it gives me a headache.” – Ava (04:56)

• Clarification: It’s “daylight saving”—no “s.” Molly admits even she learned this while researching the episode. (05:21)

2. Can You Really “Save” Daylight? (05:41–06:12)

• Reality check: You can’t store or bank daylight—just rearrange routines to match how much sun the Earth receives as it orbits the Sun.
• “We get a certain amount of sunlight each day, no matter what. We’re not in control of that.” – Molly Bloom (05:55)

3. Why Do Days Get Shorter or Longer? (06:36–10:23)

• Science Explanation by Sandon Totten:

  • Uses the metaphor of a tilted golf ball spinning and circling a giant light (the sun).
  • Our planet is tilted, so different parts get more or less sunlight depending on the time of year.
  • The further from the equator, the more dramatic the difference in day length between summer and winter.

• Memorable imagery: “When it’s summer, we’re on the top half of that golf ball, and we’re tilting more towards the sunlight, and our days are long.” – Sandon Totten (09:05)

4. History of Daylight Saving Time (14:50 – 16:23)

• Listener questions: Who invented DST and why? (14:52–15:10)
• Ancient Solutions: Romans made summer hours longer and winter hours shorter.
• Modern Adoption:
  • Originated during World War I to save energy.
  • More daylight in evenings meant less need for artificial lighting.
  • Became US law in the 1960s.
  • “These days, changing the clock doesn’t even save much energy, but we still do it.” – Molly Bloom (16:20)

5. DST Misconceptions (17:07–18:10)

• Myth Busting: Some believe DST helps farmers, but farmers actually were against it; it mainly benefits city dwellers.

• Fun quote from history:
  “...Objects to doing his early chores in the dark merely so that his city brother, who is sound asleep at the time, may enjoy a daylight motor ride at 8 in the evening.” – Gungador, reading a historical comment (17:25)

• Not Everywhere: Many regions (China, India, Hawaii, most of Arizona) don’t participate; the Navajo Nation in Arizona does.

• Halloween Factor: Candy makers lobbied for DST to extend through Halloween, giving kids more daylight for trick-or-treating. (18:10)

6. How Does DST Affect Our Bodies? (19:48–21:47)

• The Brain’s Perspective: Dwayne the Brain (talking brain character) shares how DST messes with circadian rhythms—our “internal clocks.”

  • “Sure, but for me, it’s not the time on the clock, it’s my circadian rhythm. It gets a whack, a doodle.” – Dwayne the Brain (20:21)
  • After the jump, people may have trouble sleeping, and there can be a rise in heart problems and car accidents.
  • “Daylight saving is low key terrible for our health. That’s why I’m boycotting it, not changing my clock.” – Dwayne the Brain (21:30)

• The Good News: Adjustments usually only last a week or two, and in fall you get an extra hour of sleep. (21:47)

---

Memorable Moments & Quotes

• “Maybe you decide to move time backward an hour in the mornings so you can squeeze in a few more dreams before school.” – Molly Bloom imagines having time superpowers (01:28)
• “Like, put it in a jar and keep it for later. Or store it in the sun bank.” – Molly Bloom jokes about saving daylight (05:48)
• “When your eyes see the morning rays of sunshine, that internal clock is like, ‘Wake up, buddy boy. Time to rise and shine the day away.’” – Dwayne the Brain (20:33)
• “If you could do anything you wanted with an extra hour of daylight, what would you do?” – Molly Bloom encourages listener engagement (16:23)

---

Quick Clock Facts (17:07–18:21)

• DST isn’t for farmers—mainly for city folks’ convenience.
• Not universal: China, India, Hawaii, and most of Arizona don’t observe it; the Navajo Nation does.
• Halloween extension: DST moved to early November to keep trick-or-treaters safer and give more daylight for candy collecting.

---

Fun Segments

Mystery Sound (11:06; 23:25)

• Ava and Molly attempt to guess a “mystery sound.”
  Final answer: Mixing tea in a teacup with a spoon (revealed at 24:03)

Science Chant (12:23)

• Ava (with help from her dad) invents a science cheer:
  • “Give me a Y... If you’re so curious, ask a scientist!” (12:54)

Listener Questions (14:52)

• Kids ask about who invented DST and why it exists.

Honor Roll (24:12–end)

• Shoutouts to listeners for contributions (questions, artwork, etc.).

[Ava]

You're listening to Brains on. Where we're serious about being curious.

[Molly Bloom]

Imagine you had a superpower. You can control time.

[Ava]

You can speed up the day or slow it down at will.

[Molly Bloom]

Maybe you decide to move time backward an hour in the mornings so you can squeeze in a few more dreams before school.

[Ava]

Or you jump an hour forward to skip over your dentist appointment.

[Molly Bloom]

You'd be pretty powerful. And it's kind of what we do with our clocks twice a year, you

[Ava]

know, Fall back and spring forward.

[Molly Bloom]

Those are the times when we jump ahead or backward by one hour. Or at least the clock jumps through time even if we don't.

[Ava]

Today, we're going to talk about why

[Molly Bloom]

we do that and why it might be tough on our bodies. Stay with us.

[Sandon Totten]

Hey, Gungador. How's the new job going?

[Gungador]

Very busy. Being CEO is big job even for big monster like Gangador.

[Sandon Totten]

Yeah, I've noticed that ever since we made you CEO of Brains on Universe. You haven't been at the dance studio as much as.

[Gungador]

Yeah, Gungador missed doing twirls. But some monster need to keep this place running.

[Sandon Totten]

True. Hey, you listening?

[Molly Bloom]

Yeah.

[Gungador]

he loves, sweating and twirling.

[Molly Bloom]

Yeah. Brains On. You're listening to Brains on from the Brains on universe. I'm your host, Molly Bloom, and my co host today is Ava from Minneapolis. Hi, Ava.

[Ava]

Hey, Molly.

[Molly Bloom]

So we're gathered here today to answer this question. Hi, my name is Uzam from KitchenAid. And my question is, why do we have Daylight Saving Time? So Daylight Saving Time is part of the year here in North America when we move the clocks forward an hour. It also happens in lots of other places like Europe, Egypt and parts of Australia. In fact, it's happening soon. Ava, I'm just wondering, does this change trip you up every year?

[Ava]

Not really. I kind of like having longer and shorter days.

[Molly Bloom]

Yeah, you're like, oh, this is like a fun adventure.

[Ava]

Yeah, definitely.

[Molly Bloom]

So in Minnesota, where we are, would you say it gets dark pretty early in the winter?

[Ava]

Yeah, I'd say so. Definitely.

[Molly Bloom]

Yeah. It's always a bummer when it's like 4:30 and I'm like, the sun is down.

[Ava]

Yeah, that part's not so great.

[Molly Bloom]

So what do you prefer? Getting up early and getting the morning light or staying up late?

[Ava]

I like both. But if I'd have to choose, I would say staying up late.

[Molly Bloom]

Yeah, you're a night owl.

[Ava]

Yeah.

[Molly Bloom]

So if you could choose to jump forward one hour every year, what hour would you like to skip over?

[Ava]

I would skip four to five because that's my bus ride and it's really long and it gives me a headache.

[Molly Bloom]

Oh, okay. That sounds like a really good one to skip. Yeah, good choice. So if you could go back one hour, repeat an hour, when would you use that power?

[Ava]

I think I would go back an hour at 7 o' clock so I could have more sleep before going to school.

[Molly Bloom]

Very smart. So you're like, one more hour sleep, please. By the way, you might have noticed we're saying daylight saving and not daylight savings. There's no s. Kind of tricky. I learned that when we started making this episode. But to Uzam's question, why do we have Daylight Saving Time?

[Ava]

You'd think based on the name, the idea is to save daylight. But you can't actually save daylight.

[Molly Bloom]

Like put it in a jar and keep it for later. Or store it in the sun bank.

[Ava]

Yeah, that's not going to work.

[Molly Bloom]

Nope. You get a certain amount of sunlight each day, no matter what. We're not in control of that.

[Ava]

But we are in control of our clocks and our routines.

[Molly Bloom]

Like when we wake up, when we start and end work or school, and

[Ava]

when we go to bed.

[Sandon Totten]

Good night, Ava.

[Ava]

Night, dad.

[Molly Bloom]

All would be well and good for our schedules if the sun rose and set at the same time every day.

[Ava]

Yeah, but it doesn't work that way.

[Molly Bloom]

No, sir, it does not. Here in North America, there is more daylight in the summer and less light in the winter.

[Ava]

We move the clocks forward in the spring so there is more light in the evenings, which also means there is less light in the mornings.

[Molly Bloom]

But why are the days so much shorter in the winter anyway?

[Sandon Totten]

Molly, Ava, I'm a time traveler from the present, here to help answer your question.

[Molly Bloom]

Hey, Sandin, why are you wearing that shiny outfit covered in bubble wrap?

[Sandon Totten]

Yeah, I'm a time traveler from the present.

[Ava]

Wait, if you are from the present, doesn't that mean you're from right now? How is that time traveling?

[Molly Bloom]

And it still doesn't explain the outfit. Are those swim flippers on your feet?

[Sandon Totten]

Okay, okay. I haven't traveled in time yet, but I plan to very soon. On Daylight Saving Day, I Sand in time traveling, Totten will boldly go one hour into the future. I'm wearing this bubble wrap and tinfoil cardigan with the flipper shoes because my trend forecasts say this is how people will be dressing in the future.

[Molly Bloom]

You mean one hour into the future.

[Sandon Totten]

Precisely, Molly. It's gonna be like a whole new world, and I need to blend in. Now, I've been studying this miraculous time jump for weeks, so I can help explain anything about it.

[Ava]

Actually, we were just wondering. We changed the clocks in late winter to get more light in the evening. But why is there so much less daylight in the winter anyway?

[Sandon Totten]

Great question. It actually has to do with how our planet tilts. Think of it this way. Imagine our planet is a golf ball. And imagine that golf ball is going in circles around a giant light bulb. That's the sun.

[Molly Bloom]

Okay, I am imagining it a golf ball circling a big light.

[Sandon Totten]

Great.

[Molly Bloom]

Great.

[Sandon Totten]

Okay. Now, not only is the golf ball making a big circle around that light, imagine that it's also spinning around and around, kind of like how a top spins, so it's making little twirls while it makes one big circle around the light.

[Ava]

I'm getting dizzy thinking about it, but okay.

[Sandon Totten]

Okay. So each time that ball spins around one time, like a top, that's one day. Each time, it goes all the way around that big light. That's a year.

[Molly Bloom]

Makes sense.

[Sandon Totten]

Now, if that Ball was facing the light straight on, the amount of daylight would be the same all year. But our Earth is not facing the sun straight on. It's tilted a little. So imagine you took that golf ball and you tilted it a little bit so the top half was more in the light than the lower half.

[Ava]

Okay. That top half would be seeing a lot more sun then, right?

[Sandon Totten]

Exactly. That's what it's like for us in the northern part of the globe. When it's summer, we're on the top half of that golf ball, and we're tilting more towards the sunlight, and our days are long.

[Molly Bloom]

And I'm guessing the bottom half of the golf ball, the part tilting away from the sun. That's winter.

[Sandon Totten]

100% spot on. When it's summer in the northern half of the planet, it's winter in the southern half. But here's the thing. As the Earth circles around the sun, it'll eventually get to the opposite side of that star. The tilt stays the same. But now the southern part is angled to the sun and the northern half is angled away.

[Ava]

Oh, so that's winter for us in

[Molly Bloom]

the north and summer in the south. Correct.

[Sandon Totten]

And if you live right along the middle of the planet, like the belt we call the equator, the length of the days doesn't change all that much in the summer or the winter. But when you live really far north or really far south, you can get extremely short days in the winter and very long ones in the summer. So that's why we have short days

[Ava]

in the winter, because right now, our half of the globe is tilted away

[Molly Bloom]

from the light, and so we aren't getting as much direct sunlight. Wow. Thanks for shining a light on that issue for us, Sandon.

[Sandon Totten]

No problem. Now I have to get ready for our leap forward in time. You should too. Here, eat this. It's a cereal full of riboflavin. I've heard riboflavin helps your body adjust to time travel.

[Ava]

I can really taste the riboflavin.

[Sandon Totten]

Enjoy now. I'll see you, too. In the future.

[Dwayne the Brain]

Boring.

[Molly Bloom]

Fun. No matter what the clock says, I always know when it's time for the mystery sound. Ava, are you ready for the mystery sound?

[Ava]

Yes, I am ready.

[Molly Bloom]

Okay, here it is. What do you think?

[Ava]

I think that that's maybe, like, a fork or a knife hitting a bowl with some water in it. Maybe, like, something cleaning it in the sink.

[Molly Bloom]

Okay.

[Ava]

But, yeah, I think maybe like, a fork, like, hitting a glass bowl, and then also there's some water in it.

[Molly Bloom]

Okay, so we're Hearing a utensil. We're hearing a liquid, we're hearing a bowl. Do I hear it again?

[Ava]

Yes.

[Molly Bloom]

Okay, here it is.

[Ava]

Thank you.

[Molly Bloom]

Any new thoughts?

[Ava]

Not really. Maybe like two utensils clanking against each other. But honestly, I think I have the same thought.

[Molly Bloom]

Yeah. Yeah, that sounds very convincing to me. Yeah. First thing that popped in my mind was like a spoon and a cup. Yeah, that's what was in my head. So. So I think you and I are doing a great job. Yeah. All right, so we're going to hear it again. Get another chance to guess and hear the answer at the end of the show.

[Ava]

Stick around.

[Molly Bloom]

We've got an episode coming up about baseball. It's a fun sport with lots of fun chants.

[Ava]

Like we need a pitcher, not a belly itcher.

[Molly Bloom]

Nice. But you know what doesn't have great chants? Science. It sure could use some. So make up a fun game day chant for science and share it with us. Ava, can you think of a fun cheer or chant for science?

[Ava]

Yeah. So my dad thought of one that I think.

[Molly Bloom]

Excellent. Thanks, dad.

[Ava]

It's really funny. Okay, give me a why.

[Molly Bloom]

Why?

[Ava]

Give me a why.

[Molly Bloom]

Why?

[Ava]

Give me a why.

[Molly Bloom]

Why?

[Ava]

If you're so curious, ask a scientist.

[Molly Bloom]

Bravo. I love that one. It also encourages our motions to make a Y, wouldn't you say? I can see a whole stadium doing that. I am into it. Excellent work, dad. So record your cheer or chant and send it to [e-mail] contact.

[Ava]

You can also send us drawings, jokes, mystery sounds or questions.

[Molly Bloom]

Again, that's brainson.org contact. Can't wait to hear from you. Today's episode is sponsored by bombas. It's the time of the year we think about what am I going to do differently this year? Maybe I'm going to read more. Maybe I'm going to work out more. Maybe I'm going to learn a new skill. But really at the top of my list is number one, to get comfy. And that's where Bombas comes in.

[Ava]

And I'm Ava.

[Molly Bloom]

And we're talking about daylight saving.

[Ava]

It's something a lot of you are curious about. Hi, my name is Katherine from Richmond Hill, Ontario. And my question is, who invented daylight savings and why do we have daylight savings?

[Dwayne the Brain]

Hi, my name is Micah from Queens, New York. My question is, why do we have daylight savings in the usa?

[Ava]

So we know that in the winter, days are shorter in the north because our half of the planet is tilted away from the sun. But why do we start moving clocks forward?

[Molly Bloom]

Turns out lots of people have suggested changing clocks to make up for shorter days.

[Ava]

In fact, in ancient Rome, they just changed the length of the hours to better fit the daylight.

[Molly Bloom]

So an hour was longer in the summer and shorter in the winter.

[Ava]

But moving the clock forward by an hour didn't take hold until much later during World War I.

[Molly Bloom]

It was the early 1900s, and there was a big battle across the globe. Lots of countries were fighting to save energy for the war. Some places moved the clocks forward an hour. That way there would be more daylight in the afternoon and evening.

[Ava]

The idea was that people would use less energy powering homes if they could just rely on daylight instead.

[Molly Bloom]

The war ended, but daylight saving caught on in the US and was made into law a few decades later in the 1960s. Now we still switch the clocks forward every spring to get more light after school and work. These days, changing the clock doesn't even

[Ava]

save much energy, but we still do it.

[Molly Bloom]

There's a lot more to the history of this time change, and we're gonna cover it in an episode of Forever Ago later this year. But we want to know, if you could do anything you wanted with an extra hour of daylight, what would you do? Ava, what would you do with that extra hour of daylight?

[Ava]

Well, there's a lot of things I'd want to do, but I think I would want to go over to my friend's house and play on our trampoline for an hour. Nice.

[Dwayne the Brain]

Really fun.

[Molly Bloom]

That sounds great. That's a perfect use of that hour. So, listeners, send us what you plan to do with your extra hour of evening light. Send it to [e-mail] contact. Thanks, Brainzime. Okay, time now for some quick clock facts. Tick tock. Clock facts.

[Ava]

You might have heard that one of the reasons we do daylight saving is to make things easier for farmers.

[Molly Bloom]

But that's not true. Farmers actually were against the time change.

[Ava]

They said it really only helps city workers.

[Molly Bloom]

In fact, one saucy person wrote into a popular magazine to say the farmer

[Gungador]

objects to doing his early chores in the dark merely so that his city brother, who is sound asleep at the time, may enjoy a daylight motor ride at 8 in the evening.

[Molly Bloom]

Tick tock clock. Fact, there are some places that don't do daylight saving.

[Ava]

Yeah, like China and India in the

[Molly Bloom]

US Hawaii and parts of Arizona don't observe the change either. But the Navajo Nation in Arizona does. Tick tock clock. Fat. Daylight saving used to stop on the last Sunday of October, but candy makers helped get it changed to November. That way it would still be daylight saving time on Halloween.

[Ava]

More daylight equals more time for kids to rake in that sweet Halloween candy. It also means that kids would be safer on the streets since it would be lighter longer.

[Molly Bloom]

Speaking of clocks, mine says it's time to check the mailbag. We love getting letters, emails and messages from you all. Okay. Oh, here's one. Someone made their own version of our theme song. Let's hear it.

[Ava]

Hi, Brainstorm. I am Elliot from Greenbrook, New Jersey, and this is the best that I could do of the Brainstorm theme song.

[Molly Bloom]

Nice on a keyboard and everything. Nice work, Elliot. If you want to play us a song or ask us for some advice, or if you have a joke to share, send it to [e-mail] contact hope to see your name in our next mailbag.

[Ava]

It doesn't actually say daylight, but moving the clocks forward makes it so that there's more daylight in the evenings.

[Dwayne the Brain]

Can I just say, I utterly detest daylight saving with every single one of my precious neurons.

[Ava]

Ugh.

[Molly Bloom]

Oh, hey, it's Dwayne the brain.

[Ava]

A literal brain that can talk. Yes, it's me.

[Dwayne the Brain]

I'm a brain. And I'm still absolutely wonderful. But I am not looking forward to daylight saving time. Every year.

[Molly Bloom]

It messes me up because you get confused about the time. Me too. I can never reset my car clock, so I just leave it wrong until we change time back. True story.

[Dwayne the Brain]

Sure, but for me, it's not the time on the clock, it's my circadian rhythm. It gets a whack, a doodle.

[Ava]

Oh, circadian rhythm. That's like a person's internal clock that tells them when to wake up and when to go to sleep.

[Dwayne the Brain]

Exactly. And it's controlled by daylight. When your eyes see the morning rays of sunshine, that internal clock is like, wake up, buddy boy. Time to rise and shine the day away.

[Molly Bloom]

Right. And when it gets dark, that internal clock tells your body to get tired and sleepy so you can rest.

[Ava]

Yep.

[Dwayne the Brain]

So when we jump an hour in the morning, my circadian clock is all like, what the beans? I'm supposed to wake up. And now it's too early.

[Ava]

Ugh.

[Dwayne the Brain]

And when it's evening, my clock is all like, yo, I'm ready to get cozy in my jammies. Why are we still eating dinner?

[Ava]

I feel that, too. Waking up the day after the jump is hard.

[Dwayne the Brain]

Yeah, bro. Some sleep researchers say insomnia is more common after clock changes.

[Molly Bloom]

Boo.

[Dwayne the Brain]

That and some other scientists have found links between moving the clock and heart problems in older people. And more car accidents, too.

[Molly Bloom]

That makes sense. We're not as sharp when we're groggy.

[Dwayne the Brain]

Yeah, daylight saving is low key. Terrible for our health. That's why I'm boycotting it, not changing my clock. Maybe I'll be late to appointments or early, Whatever. I don't care.

[Molly Bloom]

But scientists also say the effects of daylight saving only last a few days.

[Ava]

And in the fall, you get a little extra sleep, which is nice.

[Molly Bloom]

Also, what kind of appointments does a talking brain even have?

[Dwayne the Brain]

Important stuff. You know how Gung Gar is CEO of Brains on Universe now? Well, I'm Gun Gar's brain trust.

[Ava]

Does that mean you advise Gun Ghidorah on important business stuff?

[Dwayne the Brain]

Nah. I mean, I'm a brain he trusts. So we just tell each other secrets that we'll never share with anyone. Like how Sandin is afraid of green apples. Or how Mark sometimes sneaks off to be the backup catcher for the New York Mets. Top secret stuff.

[Molly Bloom]

Well, good luck with everything. Thanks for stopping by, Dwayne.

[Dwayne the Brain]

Later, Broskis.

[Molly Bloom]

Daylight saving happens in the US when we move clocks forward an hour in the spring.

[Ava]

The goal is to get more sunlight in the evening hours, but it also means less light in the morning.

[Molly Bloom]

It started as a way to save energy during World War I, but it became a normal part of life in certain places, like the US Moving, the

[Ava]

clocks can mess with our internal body clocks, called our circadian rhythm.

[Molly Bloom]

But the effects wear off after a week or two. That's it for this episode of brains on. This episode was produced by Molly Blue, Mark Sanchez and San and Totten. It was sound designed by Mark Sanchez, who also wrote our theme music. Special thanks to Sam and Jen Rosenbaum, also Ava's sister and the rest of her family, and Ken Taborski at Code of the north for all of their website help. Okay, Ava, you ready to go back to the mystery sound? Yes. All right, let's hear it.

[Ava]

Yeah, I think, like, maybe a spoon scooping or like, getting scooping, like, maybe water out of a bowl into, like, another bowl or like, the sink maybe. I don't know, something with silverware and a bowl and water.

[Molly Bloom]

Silverware and a bowl and water. Yeah, that's a few. Okay, I'm just gonna go out on a limb. I want to say spoon. What do you think? Spoon. Knife, Fork? Spoon. We're going spoon. Okay. Okay. Spoon. I'm committing to spoon. Should we hear for. Right. Yeah. Spinner. Fork, maybe. I don't know. Okay, here is the answer.

[Ava]

Hi, Boyenzan. My name is Kelso. That was the sound of me mixing tea in a teacup with a spoon.

[Molly Bloom]

Spoon.

[Ava]

Yes, Spoon.

[Molly Bloom]

Spoon. Spoon. Spoon. Okay, we didn't quite get the teacup part, but a teacup, tiny bowl.

[Ava]

It's a cup.

[Molly Bloom]

It's a cup, and there's liquid in it. Good job, US High fives. Now it's time for the brains honor roll.
