    	Hmmm.... we're still a good 24 days or so from the Vernal Equinox, so 
    does that mean that this period lasts around 48 days?  Or am I 
    oversimplifying the matter?
    
    	If my quick-and-dirty mental sketch is correct, there would be a 
    similar period bracketing the Autumnal Equinox, correct?
