Progressed chart: the map of time growing from the inside
In secondary progressions each day after birth equals one year of life. It does not show outer events — it shows your inner maturation.
Calculate for freeSecondary ProgressionsSecondary progressions rest on the formula 'one day equals one year'. The sky thirty days after your birth describes your inner state at thirty. Transits show events arriving from outside; progressions show what is ripening inside — which is why their effect is quiet but permanent.
The key indicator: the progressed Moon
The progressed Moon changes sign and house roughly every two and a half years, completing a full cycle in about twenty-seven to twenty-eight years. Whichever house it occupies is where your emotional focus lives. In the 4th you are in a period of home, family, roots and safety; when it moves into the 10th the need to step out, be seen and build starts.
The aspects the progressed Moon makes to natal and progressed planets deliver that period's emotional events. Feeling lonely, tired and burdened while the progressed Moon squares natal Saturn is not a coincidence — it lasts a few months and it passes.
When the progressed Sun changes sign
The progressed Sun changes sign roughly every thirty years. It is one of life's largest identity shifts: someone moving from Cancer to Leo slides from protectiveness toward visibility and self-expression. It arrives not as an event but as a change of tone spread over several years.
What 0 and 29 degrees mean in progressions
- 0 degrees: the start of a new identity cycle; inexperienced but fresh energy in that area.
- 29 degrees: a file closing; the final exam of that sign's lesson, urgency and pressure to complete.
- Progressed Moon at 29 degrees: the end of an emotional period, closing a two-and-a-half-year chapter.
How to use progressions
Never read progressions alone — pair them with the natal chart and transits. The natal chart says what is possible, progressions say what you are internally ready for, transits say which door is opening from outside. When all three point at the same subject, a genuine turning point happens.
