For a little under nine months, the Mean Black Moon crosses house 12 of your chart and makes a lack audible there, in what acts out of sight. I would like to say what this passage awakens, what it does not do, and where its answer is sought.
What a transit of the Black Moon is
A transit of the Black Moon announces nothing. I want to say this before anything else, because it is the first question I am asked. The Black Moon is not a body that acts; it is a void that moves, and for a few months it stands at one place of the zodiac and of the chart. What it does there is make a lack audible: the Call, which I described on the page Lilith, the Black Moon, makes itself heard where the Black Moon passes.
The house tells where. When the Black Moon crosses your house 12, it is in what acts out of sight, withdrawal, solitude, secrecy, what is done without witness, that the lack makes itself heard. It is not an event that happens to you; it is a place that opens, for a few months, at this point of your life.
What this passage awakens
During this transit, what was already missing in what acts out of sight can no longer be ignored. What one had soothed with more effort, more love, more success or more knowledge comes back, and it comes back this way. I often see, in people going through this passage, a precise dissatisfaction in this area, which no event explains, and sometimes an event that comes to make it visible: a departure, an ending, an encounter, a weariness. I never read these events as blows of fate. I read them as what makes the lack audible, and the lack, in my method, is a Call.
What is awakened also depends on which Black Moon is passing. The Mean sets the course of the period: what this area asks, at bottom, for nine months. The True comes and goes, and marks the days when something, in the body, can no longer be deferred; it can enter and leave the house several times. The Corrected seeks attunement between the two. The application shows all three on your chart.
Where the answer is sought
I hold this rule from the birth chart, and it holds in transit: each Black Moon has its respondent opposite it in the chart. When the Black Moon crosses your house 12, Christos, Apollo and Priapus cross your house 6 at the same time. The answer to what the passage awakens in what acts out of sight is therefore not sought in what acts out of sight, but in work and care: daily work, service, care of the body and of things. That is where something can take shape during these months, and that is where I look first.

If you have a natal Black Moon in this house
The passage becomes a return. The Mean Black Moon comes back to its natal position about every eight years and ten months, around the ages of 9, 18, 27, 35, 44, 53 and 62. These are the moments when the Call makes itself heard most clearly, and when the answer one has given it so far can be measured.
Frequently asked questions
How long does the Black Moon stay in house 12?
It depends on the size of the house in your chart. For a house of thirty degrees, a little under nine months for the Mean Black Moon. The True can enter and leave it several times around these dates.
Is the Lilith transit in house 12 a bad period?
No. It causes nothing; it makes a lack audible in what acts out of sight. The answer is sought in house 6, in work and care, and that answer decides what the period will have been.
