How do daytime hours and nighttime hours compare on the dates of the equinoxes and the solstices?

As the Earth continues its orbit around the Sun between the winter and summer solstices, daylight lengthens. At the equinoxes, sunlight strikes the Earth's equator perpendicular to the surface. Every area on the planet, regardless of latitude, has 12 hours of daylight and 12 hours of night. The length of a day at the equinoxes is about 12 hours 50 minutes.

As the Earth rotates toward the Sun at the autumnal and vernal equinoxes, daylight hours decrease and then begin to increase again at the summer and winter solstices. At the equinoxes, sunset occurs at exactly when darkness begins. But because the rotation of the Earth is not exact, sunset does not mark the end of daylight immediately after the equinoxes. Days are shorter at higher latitudes during the fall and spring, but longer at lower latitudes in the summer and winter.

The length of a night at the equinoxes is about 12 hours 50 minutes. During the fall and spring, nights are getting longer, while during the summer and winter, they are getting shorter.

These events can be used as markers for astronomers to estimate past or future times of significant astronomical events. For example, observers could use information about how long it took for light to reach them from the equinoxes or the solstices to determine where they were on the earth at certain points in time before modern instruments were developed.

What is true of the hours of daylight and darkness everywhere on earth at an equinox?

At Earth's poles, the spring equinox marks the transition from 24 hours of darkness to 24 hours of sunshine. The fall equinox follows a similar pattern, except that it is the reverse: 12 hours of darkness to 12 hours of daylight.

During a total solar eclipse, only those areas within direct line of sight of the center of the Moon are affected by its dark shadow. Regions beyond this zone see all the sunspots and stars on the solar surface as well as any clouds or haze in the atmosphere.

Areas within the path of totality experience complete darkness due to the absence of sunlight. Outside of this zone, observers see normal daytime skies full of stars with a few faint moonbeams breaking through.

Totality ends when the Moon moves out of its shadow and back towards the Sun. During this period, no more than a thin crescent is visible from anywhere on Earth.

The length of the eclipse is very location-dependent. If you live near the center of the path of totality, you will see almost an entire lunar eclipse over the course of a lengthy event. However, if you are on its edge or not involved in its central path at all, you might miss most or even all of it.

How many hours of daylight are there on either equinox at the North Pole?

12 hrs. During the equinoxes, every area on our globe (save the extreme poles) has 12 hours of sunshine and 12 hours of darkness. The vernal, or spring, equinox occurs on March 21 or 22 in the northern hemisphere (the fall equinox in the southern hemisphere). The autumnal equinox occurs on September 23 or 24.

At the north pole, where the sun is always directly overhead, daytime and nighttime are equal in length. At the south pole, where the sun is always below the horizon, night lasts all year round.

The polar regions experience four seasons over the course of a year: winter, dark days; spring, twilight nights; summer, light days; fall, more darkness again.

During a day at the north pole, the sun rises due east and sets due west, passing directly over the center of Earth. At the south pole, the sun never gets high enough to rise due east and set due west, so it passes directly over the south pole itself. A person standing at the north pole would see the stars above him/her during the day, but not at night.

At the north pole, the angle between the surface of Earth and the orbital plane of the planet is 90 degrees. At the south pole, the angle is 0 degrees.

At the north pole, the axis of rotation is perpendicular to the surface of the planet.
