    Uses of almanacs for astrology
    From: Fred Hebard
    Date: 2004 Oct 17, 18:42 -0400

    I don't know much about astrology, but the results of at least some of
    their computations correspond to the orientation of the heavens back in
    Roman times, not now.  Thus, the first point of Aries is not now in
    Aries but between Pisces & Aquarius.  This is due to the precession of
    the earth's orbit relative to the heavens.  I suppose the Nautical
    Almanac might be useful for astrological calculations, but the earth's
    orbit would have to be shifted to account for this.  I also don't know
    how the current ephemerides for the planets, as opposed to sun, match
    up between the two systems.  For astrological computations, it seems it
    would be easier to use the old ephemerides rather than our new-fangled
    ones.
