To me this question only makes sense in the context of the background stars. In other words, are the Sun's galactic coordinates (galactic longitude and latitude) always the same at the exact instant of sucessive vernal and autumnal equinoxes. The answer is still no, largely due to the precession of the Earth's axis. This causes the position of the sun at equinoxes to precess too.

As usual (but not always!) Wikipedia provides: http://en.wikipedia.org/wiki/Precession#Precession_of_the_equinoxes

Cripes, that takes some thinking about.

The only reason is doesn't work is that there is not an exact number of days in the year.

That means that when the Earth reaches one of the two points in its orbit when its axis is neither sloping towards the sun or away from the sun, it will be a different part of the day to the year before and the following year.

NO!
If the equinox occurred at exactly the same time and on the same day every year, this would happen.
But it doesn't.
