day length in north pole?

Question

Whats the day length in the north pole?

Answer 1

24 hours, just like the rest of the Earth.

But you may be asking about how long the Sun is in the sky each day. At the equator the Sun is up 12 hours and down 12 hours each day. As you go away from the equator, the tilt of the Earth's axis of rotation changes that. In winter the Sun is up less than 12 hours and down more than 12 hours. The closer you get to the poles the greater the difference. Within 23.5 degrees of the pole, the Sun can be down more than 24 hours at a time. Directly at the pole, the Sun is up 24 hours a day all summer and down 24 hours a day all winter. If you are standing directly at either pole the Earth's rotation does not make the sun rise or set. It goes completely around the horizon, without rising or setting. But as Earth orbits the Sun and tilts first one pole and then the other toward the Sun every 6 month, the Sun can be seen to gradually go lower to (or below) the horizon as it goes around, or gradually higher above the horizon as it goes around. At the poles the Sun is up continuously for 6 months of each year, and down continuously for the other 6 months.

Answer 2

North pole receives 24 hours of daylight for a few months in the summer and total darkness for months in the winter. These two annual times of light and dark are separated by a long sunrise and a long sunset.

Twice each year — during the equinoxes (“equal nights”) — Earth's axis is not pointed toward our Sun. The spring equinox in March marks the beginning of the transition from 24 hours of darkness to 24 hours of daylight at the north pole.

The fall equinox in September marks the shift into 24 hours of darkness at the north pole.
