Want this question answered?
Depends what date, Virgo is August 23rd- September 22nd and Libra is September 23rd - October 22nd.
This happens at the spring and autumn equinoxes. Equinoxes occur twice a year, when the tilt of the Earth's axis is oriented neither from or to the Sun, causing the Sun to be located over the equator. They occur on the 20th or 21st of March (spring) and 22nd or 23rd September (autumn).

Aquarius- January 20th - Feb 18th Pisces-February 19th- March 20th Aries-March 21st-April 19th Taurus-April 20th- May 20th Gemini-May 21st-June 21st Cancer-June 22nd- July 22nd Leo-July 23rd-August 22nd Virgo-August 23rd-September 22nd Libra-September 23rd- October 22nd Scorpio-October 23rd- November 21st Sagittarius-November 22nd-December 21st Capricorn-December 22nd- January 19th
days and nights are caused due to the rotation of earth on its own axis. it takes about 23 hours 56 minutes and 54 seconds for earth to complete rotation once. during rotation the part of earth which faces sun has day and the part away from sun has night. at poles days and night are of 6 months long.......when sun rays are direct on tropic of cancer there is 6 months day at the north pole and while the northern hemisphere has long days and shorter night. similar is the case with southern hemisphere. on 21st march and 23rd September days and night are equal throughout the world as the sun rays are direct on equator. areas around equator have always equal days and equal nights..............that's all i know about it
It varies from September 21 to September 24, depending on the year and the location.
as every year and everywhere on the northern hemisphere: September 23rd
The autumn equinox is September, usually the 22nd or 23rd, in the Northern hemisphere. There are two equinox, the autumnal and vernal. They are referred to these name everywhere, in both the northern and southern hemispheres.
It all depends on where you are, the northern hemisphere or the southern one. Generally speaking, in the northern hemisphere, September is considered the fall while in the southern hemisphere, September would be considered spring. However, the equinox marks the changes of seasons and September 22nd or 23rd is the normal date for the equinox. Therefore, prior to the equinox, September is technically summer in the northern hemisphere and changes to fall at the equinox. Conversely, in the southern hemisphere, prior to the equinox, September is considered winter and changes to spring at the equinox.

In 1971, spring began on 21st March at 6:38 AM UTC in the northern hemisphere and on 23rd September at 4:45 PM UTC in the southern hemisphere.
In 1964, spring began at 14:10 UTC on Friday the 20th of March in the northern hemisphere and at 00:16 UTC on Wednesday the 23rd of September in the southern hemisphere.
The equinox happens on either the 22nd or 23rd of September each year.
In the northern hemisphere, fall, or autumn, begins at the time of the September equinox, which falls between the 21st and the 24th of September inclusive, and ends at the time of the December solstice, which falls between the 20th and the 23rd of December inclusive. In the southern hemisphere, fall begins at the time of the March equinox, which falls between the 19th and the 22nd of March inclusive, and ends at the time of the June solstice, which falls between the 19th and the 23rd of June inclusive.
In North America, fall typically encompasses the months of September, October, and November. However, the exact timing can vary depending on the region and climate.
In the southern hemisphere, the fall of 2007 began on the 21st of March in time zones east of and including UTC and on the 20th of March in time zones west of and including UTC-2. In the northern hemisphere, the fall of 2007 began on the 22nd of September in the Hawaiian Islands and on the 23rd of September everywhere else.
It is the first new moon after the winter solstice in the northern hemisphere. So it is on a different day each year. In 2012 it is on the 23rd of January
