Whole-sign aspect☌ 0°
Concentrated and variable. The same whole-sign position concentrates one sign's habits, needs, and pace. Recognition comes quickly; contrast has to be invited deliberately.
Section I
Whole signs, not exact degrees
On the wheel it is drawn with the chord from Aries to Aries. Whole-sign distance compares the signs; an exact aspect in a birth chart is measured from the planets' actual degrees.
Shared instincts can shorten the distance between an idea and a coordinated response.
Where it gets hard: The same reflex may be doubled, leaving neither person to supply the missing counterweight.
Section II
Communication and repair
Familiar shorthand works best when each person still checks that the shared words mean the same thing.
A repair lands when both people interrupt the repeated pattern instead of waiting for the other to change it first.
Section III
Three settings
Love. Similarity can feel intimate, while individual preferences keep attraction from becoming an exercise in mirroring.
Friendship. Common rhythms make plans easy; outside perspectives stop the friendship from reinforcing one blind spot.
Work. Matching instincts accelerate handoffs, provided ownership is explicit enough to prevent duplicated effort.
Section IV
Orbs and birth charts
Two planets at 0° and 1° of the zodiac are 1° apart, a 1° orb from the exact 0° conjunction.
Calculate exact conjunction contacts between two charts and read each planet pair, its orb and its direction.
