Progressed Moon
Definition
In secondary progressions — the technique where one day after birth stands for one year of life — the progressed Moon is the fastest-moving body, advancing about 12-14° per progressed year. It travels through the whole zodiac in roughly 27-28 years, spending about 2.3 years in each sign and a similar stretch in each house of your birth chart. This makes it the main short-term rhythm of the progressed chart — the thing that changes most noticeably from year to year.
In Tradition
In modern Western practice, the progressed Moon works as an emotional compass: it shows where your attention, mood, and inner focus tend to settle in each period of life. The sign and house it passes through colour the tone, and its aspects to your planets mark felt shifts in daily life. Its 27-28 year journey is read as a long echo of the natal Moon's roughly 28-day phase cycle, with its arrivals in the 1st, 4th, 7th, and 10th houses marking the wheel's quarter-turns.
In Practice
An astrologer tracks the progressed Moon's position year by year (one day in the ephemeris standing for one year of life). When it moves into a new sign — about every 2.3 years — that is read as a broad shift of atmosphere; when it moves into a new house, as a shift in which area of life is emphasised. Its aspects to your birth or progressed planets are read as short developmental triggers, usually felt across 1-3 months. The progressed lunation cycle — the progressed Moon's changing relationship to the progressed Sun — is treated as a master rhythm of eight phases of about 3.5 years each, opening at the progressed New Moon and culminating at the progressed Full Moon some 14 years later.
Historical Origin
Secondary progressions were set out by Antonius Maginus around 1604 and brought into widespread use by Placido de Titis in the mid-17th century. Reading the progressed Moon as an emotional compass is largely a 20th-century modern Western development, articulated in Forrest's *The Changing Sky* (1986) and developed further in later progression writing, including Brady, Tyl, and Coppock.
