firstly, why are you counting manually? when computers do all this for you, especially Astro, it give you the + or - orb for conj, squares and opp =8'
Referring to 29' is important as they are considered critical degrees
Classic critical degrees are
0, 13, and 26 degrees of the cardinal signs (Aries, Cancer, Libra, and Capricorn);
8-9 and 21-22 degrees of fixed signs (Taurus, Leo, Scorpio, and Aquarius); and
4 and 17 degrees of mutable signs (Gemini, Virgo, Sagittarius, and Pisces). These are considered sensitive, and sometimes strengthening, points. If a natal planet is found in a critical degree, that planet is emphasized and assumes more power in the life of the native due to its placement.
Many astrologers consider 0 and 29 degrees of any sign critical degrees as well. The 0 and 29 degrees are more crisis-oriented points, especially in predictive work.
If a natal planet is found at 29 degrees of any sign, also known as the Anaretic degree, there can be some real issues with decision-making in that part of the personality represented by the energies of the planet. The native may evaluate and re-evaluate situations before making a move one day, and the next day, jump into the action without listening to himself or herself! For example, if Mars is at 29 degrees, the native may devise many plans of actions, worry excessively about the possible actions and different routes to take, and then execute a spontaneous action that is contrary to the decision!
The aspect is more important than the degree,but if I was pushed I would say 29' is 0' and 30' =1'
