Secondary Progressions Calculator
Day-for-a-year · progressed Sun & Moon · personalized reading
Your birth chart is a snapshot; secondary progressions are the film. This calculator advances your chart one day for every year lived, mapping your inner development through the progressed Sun, Moon, and angles.
Secondary progressions advance your natal chart by one day for each year of your life — so at age 30, your progressed chart is the real sky 30 days after your birth. Astrologers read it as the timeline of your inner, psychological unfolding.
The progressed Moon changes sign roughly every two and a half years and marks emotional chapters; the progressed Sun shifts about one degree per year and traces your slowly evolving identity.

FAQ
What are secondary progressions?
A symbolic timing technique where each day after your birth corresponds to one year of your life. Your progressed chart at age 30 is the actual sky 30 days after you were born, read as a map of inner development rather than external events.
What is the progressed Moon?
The fastest-moving point in the progressed chart. It changes sign about every 2.5 years and describes the emotional chapter you are in — what you need, how you process feelings, and where your attention naturally flows.
How are progressions different from transits?
Transits are the real planets in the sky right now touching your natal chart from outside. Progressions unfold from your own chart at a symbolic rate — astrologers often describe them as inner weather versus the transits' outer weather.
