Synastry aspects

Moon contacts

What the tradition holds about one person's Moon meeting a planet in someone else's chart. The older sources speak in families, a conjunction, a trine or sextile, a square or opposition, so each reading below covers its whole family.

4 readings curated here, each traced to a work and a page you can open for free. 4 longer pieces on single aspects go further into what the contact is like between two people.

Moon and Sun

Who one of you is and how the other feels line up exactly: the strongest kind of sympathy two people can share.

Which of these you two have

The synastry page lists every contact between two charts from each person's date, time and place of birth. Nothing is transmitted; it is calculated on your own device.
