Hi gypsK,
why did I say 13?
A: 1) All constellations of the Zodiac lie on an imaginary line, called The Ecliptic. The Ecliptic is the plane of the solar system; so, all palnets
and the sun travel on or very close to this line.
2) The correct length of a month should actually be 28 days, following the menstral cycle.
3) As we know it there are 365 days in one year, 24 hrs a day.
Inactuality a day is 23hrs 56min 4 seconds long.
4) If we multiply 28 x 12 = 336. subract 336 from 365, we get 29 days another month.
5) if we take the missing 4 minutes from every day of the year, and multiply that by 365, you get 1459, didvide that by 60 ( to give a hour constant)
we get 24.333331. Thats your extra day!
6) here the obvious cracker: The Ecliptic crosses into the constellation of Ophiucus (the serpent bearer)-this is between scorpius and sagittarius.
The Ecliptic in Ophiucus is 13 arc minutes in lenght.
So there you have it- thats why there should be 13 constellations. Maybe there was at one time, but the introduction of the roman calender probably
modified that.
This is why there is inconsistency when speaking about people whom are born on the cusp of a sign
