Hi there! Have you ever heard about something called daylight saving time? It’s a special time of the year when people in the United States change their clocks. In the spring, they move the clocks forward by one hour, and in the fall, they move them back by one hour. Let’s find out why they do this!
Imagine you have a friend named Julio who is curious about why we change the clocks. Well, it all starts with the word “daylight.” Daylight is the light we get from the sun during the day. You might have noticed that the sun rises in the morning and sets in the evening, creating a pattern of light and darkness.
In places with different seasons like winter, spring, summer, and fall, the amount of daylight changes. For example, in winter, it gets dark earlier, while in summer, it stays light for longer. This happens every year!
Now, imagine you live in a place where the daylight changes with the seasons. In the summer, the sun might rise very early in the morning, even before you wake up! A long time ago, people thought it would be a good idea to wake up earlier to enjoy more of that morning sunlight. But getting everyone to wake up earlier is tough, right?
That’s where daylight saving time comes in! By moving the clocks forward in spring, it’s like everyone agrees to start their day one hour earlier. This way, we can enjoy more daylight in the evening for fun activities. Plus, using sunlight means we need fewer lights, which can save electricity!
In the fall and winter, there’s less daylight, so we move the clocks back to normal. This way, we don’t have to wake up too early when it’s still dark outside. But changing the clocks doesn’t always match perfectly with the sun’s patterns. Sometimes, it might still be dark when you wake up in spring or too bright when you go to bed in summer.
Not everyone thinks daylight saving time is helpful. Some places, like Hawaii and Arizona, don’t change their clocks at all. Changing the clocks can also make people feel tired because it messes with our sleep schedules. Doctors say it can even affect our health and make it harder to focus.
So, while daylight saving time was created to help us enjoy more sunlight, people still debate if it really works. Remember, changing the clocks doesn’t change the sun or create more daylight; it just changes when we are awake to enjoy it!
That’s all about daylight saving time! Thanks for learning with us. Remember, there are always more questions to explore. Stay curious, and see you next time!
Shadow Tracking: Go outside with a friend or family member at different times of the day and observe your shadows. In the morning, afternoon, and evening, mark where your shadow falls using chalk or small stones. Notice how your shadow changes length and direction throughout the day. Discuss why you think this happens and how it relates to the position of the sun in the sky.
Sunlight Journal: Keep a journal for one week, noting the time the sun rises and sets each day. Draw a picture of what the sky looks like at sunrise and sunset. At the end of the week, compare your observations. Did you notice any changes? Talk about how these changes might affect your daily activities and why daylight saving time might be used to make the most of daylight.
Clock Craft: Create your own paper clock using a paper plate, markers, and a brad fastener for the hands. Practice moving the clock forward and backward by one hour to simulate daylight saving time changes. Discuss with a partner how moving the clock affects your daily schedule, like when you wake up, eat meals, or play outside.
Sure! Here’s a sanitized version of the transcript:

Hi, it’s Danny! Have you heard of daylight saving time? You might know it has something to do with clocks in the United States. There’s a night in the spring when many people change their clocks, resetting the time to go forward one hour. That’s the start of daylight saving time. Then in the fall, people change their clocks to go back one hour, marking the end of daylight saving time for the year.
Here, someone named Julio is curious about all this clock changing. Let’s give Julio a call now.
Hi, Julio! I have a question for you: Why do we have daylight saving time? That’s a great question! Let’s start with that first word: daylight. You already know some things about daylight, like how we get light from the sun. We see the sun in the daytime, then it sets, and it’s dark outside. There’s a pattern of daylight and darkness that repeats.
If you live somewhere with the seasons—winter, spring, summer, and fall—you might know about another daylight pattern. Let me show you what I mean. Here’s what the sky looks like when I have dinner in the winter, and this is what it looks like when I have dinner in the summer. Now, I eat dinner around the same time every day, but you can probably spot some differences in these pictures.
What do you notice about the sky in the winter compared to the summer? Now would be a good time to pause the video and discuss.
Okay, are you ready? Maybe you noticed that it’s darker outside in the winter; the sun has already set when I eat dinner. But in the summer, it’s still light; the sun hasn’t set yet. That’s because in some places, the amount of daylight changes with the seasons. There’s more daylight in the spring and summer and less in the fall and winter. It’s a pattern that repeats each year.
Now imagine you live someplace where the amount of daylight changes with the seasons. In summer, for instance, there’s sunlight starting early in the morning—so early you might still be asleep. In the past, that got some people thinking. They thought if everyone got up a little earlier, they could make use of that morning sunlight. If we did our other activities a little earlier, like earlier lunch and earlier dinner, we could fit in our evening activities before the sun sets too.
Now, daylight after dinner might sound great, but imagine if you had to convince everyone in your town to wake up early. That sounds nearly impossible! After all, everyone has their own schedule. But amazingly, that’s what daylight saving time is. When people set their clocks forward for spring daylight saving time, it’s like everyone is agreeing to wake up one hour earlier. Rather than change each person’s schedule, people in the past realized we could all change our clocks instead, and governments passed laws so that all the clocks in a place would change. That way, schools start earlier, businesses open earlier, buses arrive earlier, and so on. By changing the clocks, people can match their daily activities to when there’s sunlight in spring and summer. With that sunlight, we need fewer lights, so we can use less electricity too.
But maybe you’re curious why we change clocks again in the fall. Since fall and winter have less daylight, there isn’t much early morning sunshine to wake up early for, so we change our clocks back for those seasons. At least that’s the idea behind daylight saving time.
However, the amount of sunlight changes slowly over the seasons, and changing our clocks by an hour doesn’t always match up. It might still be dark when you wake up in spring or too bright when you go to bed in summer. With devices like air conditioners running longer on sunny summer evenings, research shows we may use more energy during daylight saving time instead of less. Changing clocks isn’t helpful for everyone’s schedule; some people are up with the sun in every season, while others work at night. Changing clocks isn’t helpful in every place; in fact, for a variety of reasons, many places around the world don’t observe daylight saving time. Some have passed laws to get rid of it, including the state governments of Hawaii and Arizona.
Whenever we change our clocks in the spring, I feel so tired the next day—maybe you do too. That’s because if you wake up at your usual time, you’re actually getting an hour less sleep that night. In the fall, when we change our clocks back, it’s like we get to sleep in an extra hour, which I don’t mind so much. But doctors point out that changing our clocks twice a year throws off our sleep schedule. It’s confusing for our bodies and can lead to worse health and more accidents. It’s hard to focus when you’re tired. That’s one reason laws have been proposed that could change daylight saving time in the United States. We might even stop doing it.
So, in summary, daylight saving time was invented to help us match our daily activities to when there’s sunlight in different seasons. By changing our clocks one hour forward, we start our days earlier in spring and summer so there will be sunlight for our evening activities too. Still, people debate how well that actually works. It’s helpful to remember that daylight and darkness follow their own patterns that we can’t change. Changing clocks doesn’t change the sun or make daylight; it just changes when people are awake to experience that light.
That’s all for this week’s question. Thanks, Julio, for asking it! Now for the next episode, we reached into our question jar and picked out three questions sent in to us that we’re thinking about answering next. When this video is done playing, you’ll get to vote on one. You can choose from: Why are four-leaf clovers so rare? Are leprechauns real? Or why do we wear green on St. Patrick’s Day? So submit your vote when the video is over. We want to hear from all of you watching. There are mysteries all around us. Stay curious, and see you next week!
