What is Latitude at which polar days begin?

Latitude is the imaginary line that tells us how far north or south we are on Earth, like steps on a staircase going around the world.

Imagine Earth is like a giant ball, and you're standing somewhere on it. If you’re near the North Pole, you might see the sun for days at a time, this is called a polar day. But if you're too far south, you won’t get that special experience. The place where polar days start happening is called the latitude where they begin.

Think of Earth spinning like a top. When one part of Earth leans toward the sun, like when it's summer there, the sun stays above the horizon for a really long time, even through night.

At about 66.5 degrees north, that’s where polar days start. It's like being on a special staircase step where you can finally see the sun not go down at all, and it starts happening from there all the way to the North Pole!

So if you're at 66.5 degrees north, you're at the starting line for polar days, the magical place where summer never really ends!
