Secondary progressions are one of the most loved timing methods in astrology, built on a simple symbolic clock: each day after your birth stands for one year of your life. This calculator finds the chart for that progressed day and returns the progressed signs of your Sun, Moon and inner planets for any date you choose.
The Day for a Year Method
To find your chart at a given age, the calculator counts that many days from your birth and reads the planets there. So your chart for the thirtieth day after birth describes your thirtieth year. The motion is real, just mapped onto a slower symbolic timescale.
The Progressed Moon and Sun
The progressed Moon is the fastest mover and the most felt, changing sign about every two and a half years and describing shifting emotional seasons. A progressed Sun changing sign, which happens only a few times in a life, marks a longer turning point in identity and direction, and is one of the headline events progressions are watched for.
How to Read Your Progressions
Begin with the progressed Moon's sign for the current emotional theme, then note whether any inner planet has recently changed sign. Astrologers often combine progressions with transits, reading transits for outer events and progressions for the inner development that meets them.
What You Need
Enter your birth date and, ideally, your birth time, then the date you want to progress to. The calculator returns each inner planet's natal and progressed sign side by side.
Common Questions
What are secondary progressions?
They are a symbolic timing method where each day after birth represents one year of life, so the chart for the Nth day describes your Nth year.
Why is the progressed Moon important?
The progressed Moon moves about one sign every two and a half years and is read as the changing emotional and circumstantial theme of each period of life.
Do progressions replace transits?
No. Many astrologers read both, using transits for outer timing and events and progressions for the slower inner development that unfolds alongside them.
