I googled the Fall Equinox 2006, and some of the sites said it's actually on Saturday, the 23rd! Today is Mabon, I think (Pagan celebration of the equinox), and when someone on my flist posted about it, I just jumped to "first day of fall!" But other sites say the 22nd, like your dad, and if NASA agrees with your dad, then they're probably right!
