AT A GLANCE
A conjunction occurs when two chart factors lie at or near the same zodiacal longitude. Astrologers read it as a close combination of functions. It can concentrate activity or make the functions difficult to separate; it is not inherently harmonious or difficult.

Geometry and orbs #
Exact means 0° separation. If the Sun is at 12° Taurus and Mercury at 15° Taurus, they are 3° apart, so a reader using a 3° or wider orb would count a conjunction. An orb is the permitted distance from exactness. Different schools and planets use different allowances.
Interpreting the relationship #
Combine the functions before reaching for a judgment: Venus concerns attraction and values, while Saturn concerns limits and responsibility. A Venus–Saturn conjunction might frame questions about commitment, caution or standards in relating. Whether those are helpful depends on the actual situation and the broader chart.
A practical example #
Imagine someone taking a creative partnership seriously enough to define responsibilities. The combination may describe sustained commitment, but it could also prompt discussion of whether criticism is crowding out enjoyment. The aspect is a relationship between symbols, not a predetermined event.
What the aspect does not establish #
Two planets in the same sign are not necessarily conjunct by degree. Conversely, planets near a sign boundary can form an out-of-sign conjunction if the chosen orb permits it. Record the actual degrees and convention. Traditional treatment of a planet very close to the Sun has additional rules that a generic ‘blending’ description cannot replace.
