Crossings
Moon–Jupiter crossing
A full table and an open door. Where a Moon line crosses a Jupiter line on your map, both planets were on angles at the moment you were born, and the latitude through that point is a Moon–Jupiter paran.

What the Moon–Jupiter crossing means
Jupiter is exalted in Cancer, the sign the Moon rules, which is why the tradition treats Moon–Jupiter as the happiest meeting of home and plenty. Their crossing is read as a big table: room for guests, children, lodgers and relatives, neighbours who lend things, and a public that's well disposed before you've done much to earn it.
Jupiter on the IC with the Moon rising is the classic one for land, space and a house that keeps getting fuller. The Moon on the MC crossing a setting Jupiter suits anyone whose business depends on people coming back, such as a restaurant, a guesthouse, a school or a practice with a waiting list, and brings patrons and partners who are generous with their time. Jupiter rising over a Moon on the IC makes you the host, the one who tells friends to come and stay.
The Moon–Jupiter crossing fills up faster than you planned. Weight, spare rooms, commitments to family and the number of people who think they can drop round all grow here, and none of it feels like a problem in the first year.
Where they meet on your map
Your Moon MC and IC lines run from pole to pole, and so do your Jupiter ones, so those four never meet. Each of them crosses the other planet's rising and setting curve once, which makes up to four crossings of a meridian line with a horizon line, and the rising and setting curves of the two can cross each other as well. Where they fall depends on the moment you were born: every chart has them, though some land in the middle of an ocean or too near a pole to be drawn.
At a crossing both planets were on angles in the same place at the same moment. Move east or west along that latitude and the same two still reach their angles together, only at another time of day, so astrocartography reads the whole latitude as a Moon–Jupiter paran. Zenith Map draws it as a band 1° (about 110 km) either side, and its weight in a place's score fades with distance from the latitude.
Birth time
A wrong birth time moves every line, and the crossings with them: an hour's error puts each crossing 15° of longitude east or west, more than 1,600 km at the equator. Paran latitudes usually stay put, because they depend on where the two bodies were in the sky rather than on the time of day, but the Moon is the exception. It moves about half a degree an hour against the stars, so an hour's doubt shifts a Moon paran's latitude by around three quarters of a degree, sometimes two or more, which is enough to take it off a city. With the Moon in the pair, both the crossing and the paran need a good birth time. What a doubtful birth time does to a map.
Questions
Is the Moon–Jupiter crossing good for a family home?
It's one of the more generous crossings for one, read in the tradition as space, comfort and a household that grows. Where Jupiter sits on the IC it leans towards land and a bigger house; where the Moon does, towards family close by. It says nothing about property prices, which belong to the market.
Is the Moon–Jupiter paran lucky?
Astrocartography reads it as goodwill more than luck: people are kind, help turns up and the public tends to like you. The catch is excess, so it's lucky for a household and less so for a waistline or a budget.
