Um, not really. My reading of the very first line of the site is that March 21 as vernal equinox is a fixed input, a core assumption of the model. Thats fine for 100-200 year spans, which is what I suspect the model is used for. Its not fine for 13000 years out. "For the six Atmosphere-Ocean Model simulations (C089, C090, C091, C092, C093, C094) used by this current web site, all years have exactly 365 days and vernal equinox always occurs on March 21, hour 0." > > You are confusing precession with > > nutation > > I have been an astronomy buff for 38 years and am not > confused easily.

So asking a second time, as a learned bright guy with 38 year experience in astronomy, how exactly do you define precession of the equinox?
