Luma
The name is a little misleading the first time you meet it. “Progressed” sounds like a path toward something, almost a roadmap. What it actually describes is quieter than that: the planets from your birth chart keep moving on paper, following a fixed rule of correspondence, never their real position in the sky today.
What a progressed chart isn’t
Don’t confuse it with a transit. A transit is where the planets sit right now, compared against your birth chart, the way how to read your birth chart, minus the jargon explains. A progressed chart never looks at today’s sky at all. It applies a fixed formula to your birth chart and tracks where that formula carries your planets, years later.
It isn’t a dated horoscope either, and it isn’t an announcement of what’s coming. A progressed chart never says “this event happens at this age.” What it points to instead is which inner tone, which emphasis, gains weight during a given stretch of your life, building on what was already sitting in your original chart.
One day, one year
The most common method is called secondary progression. The rule: each day following your birth stands for one year of your life. If you’re 30, your progressed chart is built from the planetary positions on the thirtieth day after you were born, not from today.
That shift changes everything about how fast the planets appear to move. In the real sky, the Moon crosses a sign in two or three days. In a progressed chart, those same two or three days stand for two or three full years. The motion slows down dramatically, which actually matches the real pace of inner change far better than the pace of today’s sky ever could.
| Progressed planet | Approximate speed |
|---|---|
| Moon | About one sign every two and a half years |
| Sun | About one sign every thirty years |
| Mercury and Venus | Close to the Sun’s pace, sometimes retrograde for long stretches |
| Mars and the outer planets | Barely move across an entire lifetime |
The progressed Moon, the clearest marker
Because it moves faster than every other progressed planet, the Moon is the most useful one to track. It crosses all twelve signs in a little under twenty-eight years, roughly two and a half years per sign, slow enough to mark a real period of life, fast enough that you can actually notice it happening.
A progressed Moon changing sign often lines up with a shift in what you need emotionally day to day. Moving from a progressed Moon in Virgo, oriented toward order and practical usefulness, to a progressed Moon in Libra, more attentive to relational balance, doesn’t cause anything on its own. It simply makes a need that was already forming more visible.
The progressed Sun: a shift in emphasis, not in destiny
The progressed Sun moves so slowly it rarely changes sign within a lifetime. When it does, usually just once around your thirties or forties depending on your birth time, that shift marks a long, gradual move in your personal center of gravity, not a sudden turn.
That shift always reads in relation to your birth chart, never on its own. A natal Sun in Cancer progressing into Leo doesn’t turn into a different person: the base stays the same, a different emphasis simply takes up more room, the same way natal planets keep talking to each other through the aspects between them, covered in chart aspects: how the planets actually talk to each other.
Reading your own progressed chart
For the reading to mean anything, you first need your birth chart nailed down precisely: birth time, place, exact degrees. A progressed chart builds on that foundation, it never replaces it. Looking at which house your progressed Moon is passing through also helps locate which area of life is involved, the same logic laid out in astrological houses: what they actually describe.
The real use of a progressed chart is giving language to something you may already sense: that vague feeling that your priorities have shifted over the last few years, without any single event fully explaining it. A progressed chart puts words to that slow shift. It doesn’t cause it.
That’s exactly the principle Luma runs on: your birth chart calculated to the exact degree, its slow progression explained in plain language, checked against what you actually notice about yourself, month after month. Not a schedule of things to come, more accurate words for what’s already shifting in you.
