Day and night are equal at?

Answer 1

Equal periods of sun-up and sun-down are all near March 21 and September 21,

everywhere on earth, including the equator.

Those days are often called the "equinoxes", but the equinoxes are actually the

points in the sky where the sun appears to be located on those days.

Answer 2

At the "equinox"; "equi-" from "equal", and "nox" from the Latin word for "night". The equinoxes are generally on March 21 and September 21 each year, plus or minus one day because of the cycle of leap years. The US Naval Observatory has a web site for "Earth's Seasons" at which you can see the precise times of the solstices and equinoxes.

Answer 3

One of them is named "March 21st", and the other is named "September 22nd".

They are the days during which the sun appears to reach the two points among the stars

known as the "equinoxes".

Answer 4

• March 21 and September 23
• There are 2 days known as equinoxes. March 22 and September 22.
• Equinox. There is a spring equinox and an autumn equinox.
• Equinox Occurs Twice Yearly.
• The days vary. It happens twice per year. Those days are called "equinoxes." There is the Spring or Vernal Equinox and the Autumnal Equinox. The Vernal Equinox coincides roughly with Easter and comes near the first day of Spring. Likewise the Autumnal Equinox coincides roughly with the first day of Fall. Check the Farmer's Almanac. They used to give the dates. Also astrologers keep track of these dates.

Answer 5

days and nights are of equal duration during an equinox.An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the center of the Sun being in the same plane as the Earth's equator. The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name "equinox" is derived from the Latin aequus (equal) and nox (night), because around the equinox, the night and day are approximately equally long. It may be better understood to mean that latitudes +L and -L north and south of the Equator experience nights of equal length.

At an equinox, the Sun is at one of two opposite points on the celestial sphere where the celestial equator (i.e. declination 0) and ecliptic intersect. These points of intersection are called equinoctial points: classically, the vernal point and the autumnal point. By extension, the term equinoxmay denote an equinoctial point.

An equinox happens each year at two specific moments in time (rather than two whole days), when there is a location on the Earth's equator where the center of the Sun can be observed to be vertically overhead, occurring around March 20/21 and September 22/23 each year.

Answer 6

When day and night are equal around the world (North and South Hemisheres) it is called a equinox. In a year that happens twice, once in the Spring which called a Spring Equinox and once in the Fall which is called a Fall or Autumn Equinox. Spring Equinox occurs on March 21 and Fall or Autumn Equinox occurs September 22

Answer 7

The equinox, which is on March 21 and September 21 (plus or minus one day, depending on the cycle of leap years) each year.

Answer 8

During the spring and autumn equinoxes, March 21st and September 21st.

Answer 9

During the equinoxes, day and night have almost the same length.

Answer 10

Day and night are equal all over the world at the vernal and autumnal equinoxes.
