How many hours of daylight are there at the equator?
153138
depends....it always changes.......seeing how the Earth's tilt on its axis changes the distance and the amount of direct and indirect rays from the Sun. You should research it on google or yahoo.

There is no day of the year that has EXACTLY 12 hours of daylight and 12 hours of dark because no day is EXACTLY 24 hours long. A sidereal day is 23 hours, 56 minutes, 4.091 seconds long. On the equinoxes, we have approximately equal amounts of light and dark.

The closer a country is to the equator, the more direct sunlight it receives year round. Adding about 20 degrees to the average high temperature compared to countries like the USA.

This condition prevailed until 1884, when a system of standard time was adopted by the International Meridian Conference. Earth's surface was divided into 24 zones. The standard time of each zone is the mean astronomical time of one of 24 meridians, 15 degrees apart, beginning at the Greenwich, England, meridian and extending east and west around the globe to the International Date Line. (This system was actually put into use a year earlier by the railroad companies of the U.S. and Canada, who, until then, had to contend with some 100 conflicting local sun times observed in terminals across the land.)

The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers).\nBut, if you measure the earth through the poles the circumference is a bit shorter - 24,859.82 miles (40,008 km). This the earth is a tad wider than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

The Earth rotates once in 24 hours, and its (equatorial) radius is 3,963 miles (6,378 km). As with the Moon, the rotational speed starts at zero at either geographic pole and increases as you head toward the equator, where it reaches its maximum of about 1038 mi/hr (1669 km/hr). At 45 degrees north or south latitude, the rotational speed is about 0.7 of this maximum speed.

As you get closer to the equator, the length of sunlight in a day becomes more stable throughout the year. On the equator, days have 12 hours of sunlight and 12 hours of darkness all year long. As you move north, the days become shorter in the winter and longer in the summer. \n\nTo get to your question, the days are only longer in Florida during the winter, because Florida is closer to the equator than New Jersey. During the summertime, the days are longer in New Jersey.

Theoretical there should be 24 as there is 24 hours in a day and each time zone is 1 hour long. But there are countries that have their time zones set at half hourly intervals, such as India and Australia to name two. In actual fact there is 27 time zones in the world counting these half hourly ones.

Depending on its position in the oval orbit it has around the sun, the earth gets sunlight 8.317 minutes after it is emitted from the sun.

On it's axis I presume. I'm afraid it's not definitive at all:\n\n25 days at the equator\n27 days 35 degrees of latitude from the equator.\n33 days 75 degrees of latitude from the equator.\n\nThis is for the "surface" of the sun.

Actually, it's "equinox" that means equal night.\n\nOn the equator, the days and nights are always 12 hours long (not exactly, the width of the sun's disk plus the effects of atmospheric refraction make the days a few minutes longer than the nights). The tilt of the earth's axis affects the path the sun takes across the sky, but not the length of the day.\n\nOn the equinoxes, and at no other time, the length of the day and night is 12 hours the whole world over (except right at the poles), because the plane containing the tilt of the earth's axis is at right angles to the direction between the earth and the sun - that is, the axis is not pointing at all toward or away from the sun, and the poles are equidistant from the sun.

The earth rotates 1 on its axis every 24 hours.  Hipparchus proposed dividing the day equally into 24 hours which came to be known as equinoctial hours (because they are based on 12 hours of daylight and 12 hours of darkness on the days of the Equinoxes). Ordinary people continued to use seasonally varying hours for a long time. Only with the advent of mechanical clocks in Europe in the 14th Century, did the system we use today become common place

An equinox in astronomy is the moment when the Sun passes over the equator. The event occurs twice a year, around March 20 and September 23. The word equinox derives from the Latin word for equal night. The equinoxes are the two days each year when the middle of the Sun is an equal amount of time above and below the horizon for every location on Earth.

An equinox (Latin for equal night) is the day/night of 12 hours each that takes place when the sun crosses the Equator on March or Sept. 20 (or close). The solstices are the times when the sun is directly over the Tropic of Cancer  or Capricorn, on June or December 21, plus or minus. It's how we determine our calendar.

About 8.\n\n\nTo clear up any  ambiguity contributed here by some--- The average distance from the Earth to the Sun (or 1 astronomical unit) is 8.317 light minutes. Saying it's "more" or "less" sometimes is stating the obvious-- it's an AVERAGE. Saying it's "usually" different than its average, is nonsensical. \n\nhttp://en.wikipedia.org/wiki/Light_minute
