I have seen two versions of conjunctions before. One says that a conjunction is any planet in the same sign, so for example by Venus and Moon are both in Gemini so they are conjunct.

However, I have also heard that a conjunction is anything within 30 degrees. So if your sun is, for example, at 0.00 degrees Aries than a conjunction to that would be anything up to 15 degrees Aries but also anything after 15 degrees Pisces.
I see the second version most often in composite/synastry charts.
Which is right or are they both right?
