That is depending on what you regard as the autumnal equinox. The autumnal equinox in the northern hemisphere is in September and it marks the start of autumn. In the Southern Hemisphere the autumnal equinox is in March and it marks the start of autumn. So looking at in that way, you can say yes. Of course those are two different dates on the calendar, so the autumnal equinox in one is happening at the same time as the spring equinox in the other. It is the same equinox, but where on Earth you are, determines which equinox it is. As autumn starts in one hemisphere, spring is starting in the other. So on that basis they don't mark the start of autumn in both hemispheres. It is never the same season in both hemispheres.

What happens when both hemispheres receive the same amount of sunlight?
The vernal or autumnal equinox happens.
Occurs when the sun is directly over the equator?
Equinox:)The sun is directly over the equator at the two instants during the year whenthe sun reaches one of the "equinox" points among the stars. That happens inMarch and September.Those moments are the astronomical beginning of Spring or Fall in both hemispheres.
How long is the Jupiter equinox?
The Jupiter equinox is about 3.3 Earth years long, which is equal to roughly 12,173 Earth days. During this time, both hemispheres of Jupiter receive almost equal amounts of sunlight.
What is the position of the earth near the end of both March and September?
At the end of March and September, the Earth is at equinox. During these times, the Sun is directly above the equator, resulting in equal lengths of day and night across the globe. This marks the transition between seasons and is known as the vernal equinox in March and the autumnal equinox in September.
What month do the hours of daylight and darkness in are the closest to the hours of daylight and darkness of March?
The month in which the hours of daylight and darkness are closest to those of March is September. This is because both months are near the equinoxes, when day and night are approximately equal in length. In March, the vernal equinox occurs, and in September, the autumnal equinox does, resulting in similar day length patterns.
What happens when both hemispheres receive the same amount of sunlight?
The vernal or autumnal equinox happens.
What times of the year do both hemispheres receive the same amount of energy from the sun?
Equinox (autumnal or spring)
In the northern hemisphere in what month is the autummal equinox?
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.
Do equinoxes occur in both hemispheres at the same time?
Yes, equinoxes occur simultaneously in both the Northern and Southern Hemispheres. During an equinox, the sun is positioned directly above the equator, resulting in nearly equal day and night lengths across the globe. This phenomenon happens twice a year, around March 20 (vernal equinox) and September 23 (autumnal equinox). Thus, both hemispheres experience the equinox at the same moment.
What day and night is the same length of the autumnal equinox or the vernal equinox?
Both.
The beginning of spring in the Northern Hemisphere is marked by what?
The Spring Equinox. This is the day that both both daytime and nighttime are functioning in the exact same span of time. (IE. Daytime = 12 hours, Nighttime = 12 hours = Spring Equinox.)
What is autumnal vernal equinoxes?
The equinox is either vernal (spring) or autumnal. It can't be both. But spring in the northern hemisphere is autumn in the southern.
An equinox occurs on the same day at the same time in both hemispheres?
Correct. The March equinox, which is typically March 21 but can vary by a day either way, is the spring equinox in the northern hemisphere, because the Sun us rising into the northern hemisphere. At that very same moment, it is the autumnal equinox in the southern hemisphere, because as the Sun is moving INTO the northern hemisphere, it is moving away from the southern hemisphere. The September 21 equinox sees the Sun moving south of the equator, so the spring equinox in the south, while it is the autumnal equinox in the North.
What is the word used in the name of both days when autumn and spring officially begin?
Equinox (Vernal and Autumnal)
On the fall equinox the hours of daylight are less than the hours of darkness?
No. The hours of darkness and day light are equal during autumnal equinox. (Both 12 hours)
Occurs when both hemispheres receive an equal amount of sunlight?
Polar regions
What is vernal and autumnal equinox mean?
it will fall on the 22nd September 2012 in the Northern Hemisphere. During an equinox the length of day and night in both hemispheres is very much the same . 12 hours day and night. After this date in the northern hemisphere the days will become shorter with the advance of winter
