In a birth chart

A life arranged around other people, and usually around one person.

Leo says this position favours general popularity, gives a fondness and a real ability for music, poetry and the fine arts, and makes the native affectionate, good natured and kind in manner, so that friends come easily.

Then he says something sharper. Much of the fate and many of the events of the life come about through association with other people, and the native is greatly swayed by them, generally by some one person. It tends strongly to partnership, not only in business but in nearly everything, and works best alongside someone rather than alone.

Where the tradition places it

The tradition gives the Moon no special strength or weakness here.

There are only four signs where the Moon has a formal dignity. It rules Cancer, is exalted in Taurus, is in detriment in Capricorn and is in fall in Scorpio. In the other eight, including this one, the tradition treats it as a guest that takes the colour of the house it is standing in.

So the reading of these days comes from the sign itself rather than from the Moon's standing in it, which is what the section below sets out.

The doctrine of the elements and the modes, and habit built on top of it

What these days are used for

Agreements, company and repair of a relationship.

  • AirBetween peopleAir moves between people. The tradition gives these days to talking, writing, arranging and deciding, and warns that nothing feels settled while they last.
  • CardinalOpeningA cardinal sign opens a season, so the two and a half days are read as an opening: the impulse is to begin.

The tradition gives these days to meeting and to settling, and warns that a decision made alone now tends to be made twice.

This is tradition and habit, not a measured effect. It is here because it is what the sources say, and each part carries the name of the source it came from.

Questions people ask

How long is the Moon in Libra?

About two and a half days each month. The exact length changes a little because the Moon's speed changes, and the table above gives the real figure for each crossing.

Is a Libra Moon the same as being a Libra?

No. A Libra Sun means the Sun was in Libra at your birth, which is late September to late October. A Libra Moon can happen in any month of the year.

Does the Moon sign depend on where I was born?

The sign itself is the same everywhere at the same moment, because it is measured from the centre of the Earth. What changes with your place is the local clock time it starts and ends, which is exactly what decides your sign if you were born near a crossing.
