Why does time seem to fly?

Time seems to fly because new things happen more often when you're little, and they make time feel shorter.

Imagine you have a big box of toys. When you're 5 years old, you get to play with all the new toys every day, like legos, cars, or even that sparkly unicorn your friend gave you. Every new toy feels like a whole new adventure, and it makes time go by fast.

But when you’re older, you might not get as many new toys each day. You already know how to play with the legos, maybe even built a castle! So time doesn’t feel as exciting anymore, and it seems to slow down.

What about your birthday?

When you're 5, one year feels like forever because it’s so much bigger than your whole life. But when you’re 10 or 20, one year is just a small part of what you’ve already lived through, like adding one more cookie to a big cake.

So time seems to fly when there are lots of new things happening, and it slows down when everything feels familiar!
