Oh?  But the Navy recently changed how the Equinox date in computed in
their Almanac. (http://aa.usno.navy.mil/publications/docs/almanacs.html#astalm).

The Formula for computing the Equinox changed, which formula is
dependent upon the "ascending node of the Moon"
(http://aa.usno.navy.mil/publications/docs/update.asa01.html)

        TIME SCALES AND COORDINATE SYSTEMS,Section B

        Page B6, The equation of the equinoxes and the
        paragraph following should read:

        equation of equinoxes = 1/15(Dy cose + 0."002
                                    64 sin W + 0."000063
                                    sin 2W)

        where Dy is the total nutation in longitude,
        e is the mean obliquity of the ecliptic and
        W is the mean longitude of the ascending node of the
        Moon. The equation of the equinoxes is tabulated
        on pages B8-B15 at 0hUT for each day and
        should be interpolated to the required time if full
        precision is required.

Note that Dy and e and W are shown as symbols on the web page.
