A day on Earth is 24 hours long, but not every day has 12 hours of daylight and 12 hours of night. The actual time of one Earth rotation is a little shorter–about 23 hours and 56 minutes. This opens in a new window. Daytime is shorter in winter than in summer, for each hemisphere.

How long is a day on the sun?
The sun, “a big ball of flowing, gassy plasma,” is so big that at its equator a day would be about 24-and-a-half earth days, but at its slower moves poles it would take about 34 earth days.
In which country there is always day?

The duration of day and night is almost equal at the equator because the Equator lies exactly halfway between the two tropics and on the Solstices the Sun is directly over one of the tropics and on the Equinoxes the sun is directly over the equator.
What would happen if Earth had no tilt?
If earth did not tilt and orbited in an upright position around the sun, there would be minor variations in temperatures and precipitation throughout each year as Earth moves slightly closer and farther away from the sun. Basically, we would not have any seasons.

* Based on mean solar day. Numbers provided by the International Earth Rotation and Reference System Service (IERS). The Earth’s rotation slows down over time. Modern timekeeping defines a day as the sum of 24 hours—but that is not entirely correct.
