Why do we celebrate birthdays?
We celebrate birthdays to say hooray, you're here, and you're one year older!

Pip’s answer
- We celebrate birthdays to say hooray, you're here, and you're one year older!
- In one year, Earth travels all the way around the sun.
- So each birthday, you've ridden one whole trip around the sun! Wheee!
- Ooh, people all over the world celebrate with songs, treats, and hugs!

For grown-ups
A birthday marks one complete orbit of Earth around the sun since you were born, about 365 days. People around the world celebrate in different ways, with special foods, songs, games and traditions, to show someone they're loved and to mark growing up.
Ask your child: How many trips around the sun have you taken?
