What is June 21?

June 21 is the longest day of the year in many places, like where you live.

Imagine you're playing outside with your friends on a really sunny day. The sun stays up for a long time, so you can play longer before it gets dark. That’s what happens on June 21, the sun shines the most in the sky, and the day feels extra long.

Think of Earth like a spinning top. It turns around the sun, and sometimes one side faces the sun for more time than the other. On June 21, your part of Earth is tilted toward the sun, that’s why you get the most sunlight on that day.

It's like when you stand close to a lamp, you see more light than when you move away from it. So June 21 feels like standing right next to a super bright lamp in the sky!
