No, it moves slightly forwards and backwards in time, but within a 12 hour period due to the Earth's wobble that is separate from the Procession of the Earth's poles. So in some years it can occur on the 20th of September, and other years on the 21st.

∙ 12y agothe order of the seasons is: Spring, Summer, Autumn, Winter, Spring, Summer....
if that doesn't answer your question, the autumn equinox occurs 1 season after summer, and 3 seasons before summer.

∙ 12y agoIt's more accurate to say that the autumnal equinox marks the beginning of fall in each hemisphere. The northern hemisphere's autumnal equinox marks the beginning of the northern hemisphere's fall, and the Southern Hemisphere's autumnal equinox marks the beginning of the southern hemisphere's fall.

At what time will the Autumnal Equinox occur today?

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.

Does the autumnal equinox mark the beginning of fall for both hemispheres?
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.

The vernal equinox, and the autumnal equinox, happen in a single moment for the entire globe; they are not on-going phenomena that start at one time and end at a later time. The vernal equinox (in the north) will be March 20 2013 at 11:02 UT, which is for all practical purposes the same as 11:02AM, Greenwich Mean Time.
