Secondary Progressions
A day for a year: the oldest and steadiest way of turning a birth chart into a moving one.
Read inside a cast chart: you will find it in the Predictive panel, once a natal chart is cast.
What you get
- Secondary progressions — one day after birth for each year of life
- Solar arc directions, every planet advanced by the arc the Sun has travelled
- Converse directions, running the method backwards
- The progressed Moon with its sign ingresses and phase
- Progressed aspects at tight orbs, so the dates mean something
How it works
Secondary progression maps a day onto a year. The chart for the fourth day after your birth describes your fourth year; the thirtieth day, your thirtieth year. It is a symbolic correspondence rather than a physical one, and it has been in continuous use for centuries because it works well enough to have survived.
The progressed Moon is the part most people feel. It moves roughly a degree a year and changes sign every two and a half — slow enough to describe a mood that lasts, fast enough to actually change. Its ingresses are among the most reliably noticeable dates the technique produces.
Solar arc is the blunter cousin: take the distance the progressed Sun has moved from its natal place, and advance everything by that same arc. Because all the planets move together, solar arc tends to produce fewer, sharper contacts than secondary progression.
Progressed aspects are computed with tight orbs — one degree, and half a degree for the quincunx. A wide orb on a technique this slow would smear a date across several years and tell you nothing.
