    spring equinox was on earth 20/03/2004 at 06:49 utc according to Jean Meeus' sky calender 2004

    On which planet does it occur at 6:48 ????

    Using the Nautical Almanac and interpolating between .8' South at 0600 utc and .2' North at 0700 utc the equinox calculates to occur at exactly 0648 utc.  Are you saying that Jean Meeus' sky calendar is more accurate than the nautical almanac?  Does he carry his calculations out to more precision than .1' of declination?  And who cares anyway, it's cold as most winter days here regardless of what the calendar says.
