Crossings
Moon–Mars crossing
Feelings with the heat turned up. Where a Moon line crosses a Mars line on your map, both planets were on angles at the moment you were born, and the latitude through that point is a Moon–Mars paran.

What the Moon–Mars crossing means
Moon–Mars puts heat into the part of life that wants to feel safe. Astrocartography reads the crossing as feeling turned straight into action: you defend people, cook, clean, renovate, move furniture at eleven at night, and lose your temper faster than usual over the same small things.
The kitchen is the textbook Moon–Mars room, fire and food at once, and the tradition gives this pairing to cooks, emergency carers and anyone whose care has to be quick.
On a Moon–Mars crossing, which angle Mars holds matters more than which the Moon holds. Mars on the IC crossing a rising Moon brings the heat home: building work, rows over chores and a house you'll have to fight for and then love. Mars rising across a setting Moon makes you the one who charges in, with a partner or housemate left carrying the mood. With the Moon on the MC and Mars on the Descendant, the public sees you campaigning, and a local cause or a rival business gives the crossing its purpose.
Sleep is usually the first thing a Moon–Mars crossing takes, and it's the honest test of whether the place suits you. The tradition is kinder to night births here, because the Moon and Mars both belong to the night sect and Mars counts as the milder malefic for anyone born with the Sun below the horizon. A natal Moon–Mars square or opposition is the other thing to check, since this is where it will show.
Where they meet on your map
Your Moon MC and IC lines run from pole to pole, and so do your Mars 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–Mars 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–Mars crossing bad?
No, though it's lively. Astrocartography reads it as quick feeling and quick action, which brings arguments at home as readily as the energy to renovate a house or stand up for someone. It suits active, practical people better than anyone who needs quiet to recover.
Does a Moon–Mars paran mean arguments at home?
More of them, in the classic reading, mostly short and over small things. Rooms with doors that shut, a routine with exercise in it and work that spends the energy outside the house keep them in proportion.
