Free Progressed Chart Calculator (Secondary, Tertiary & Minor Progressions)

This free progressed chart calculator generates your progressed chart with full interpretation, covering secondary, tertiary, and minor progressions in one report. Progressions describe the gradual development of a natal chart through time. Each symbolic system moves the birth chart forward according to a specific astronomical rhythm. By studying these movements astrologers observe how inner awareness, emotional patterns, and personal priorities change throughout life.

This report generates three progression charts together. Each system reflects a different level of inner development and psychological timing. When studied together they provide a detailed picture of how the natal chart unfolds over months, years, and longer life phases.

The progression charts in this report include:

• Secondary Progressions
• Tertiary Progressions
• Minor Progressions

Each chart reveals a different rhythm within the same underlying birth pattern.

Guide to Generating Your Progression Charts

Birth Date and Time: Enter the same accurate birth information used for your natal chart. Progressions depend on the original chart positions, so precise birth data ensures reliable results.

Current Date: The progression charts are calculated for the date you choose. This shows the symbolic positions of the progressed planets for that moment in life.

Chart Calculation: The system automatically calculates all planetary positions, houses, and aspects for the three progression methods.

What Are Secondary Progressions?

Secondary progressions are one of the most widely studied symbolic timing systems in astrology. This method follows the principle that one day after birth corresponds to one year of life. To create a secondary progressed chart, astrologers move the natal chart forward from the birth moment by the same number of days as the person’s age in years. The planetary positions on that symbolic day form the progressed chart for that stage of life.

Because planetary movement in this system is slow and gradual, secondary progressions reveal long phases of personal development. They describe shifts in identity, emotional priorities, personal direction, and psychological growth that unfold across many years. Particular attention is often given to the progressed Moon. Its movement through the zodiac reflects emotional cycles that shape different stages of life and highlight changing areas of attention and personal experience.

What Are Tertiary Progressions?

Tertiary progressions follow a symbolic rhythm connected with the lunar cycle. In this system one day after birth corresponds to one lunar month of life. The chart is advanced forward from the birth moment according to the number of completed lunar months lived. The planetary positions on that symbolic day describe the internal atmosphere of that period.

Tertiary progressions move faster than secondary progressions and often correspond with shorter emotional cycles. They can highlight periods of reflection, adjustment, and changes in perception that develop within longer life phases. Astrologers study tertiary progressions to observe the subtle emotional climate surrounding important experiences and personal transitions.

What Are Minor Progressions?

Minor progressions form another symbolic timing system based on the lunar cycle. In this method one lunar month after birth corresponds to one year of life. The natal chart is advanced forward according to this lunar rhythm, creating a progressed chart that reflects gradual emotional development across the years.

Minor progressions often reveal subtle changes in mood, motivation, and personal outlook that evolve quietly beneath external events. These movements can describe the emotional background that accompanies the longer developmental phases shown by secondary progressions. When studied together with tertiary and secondary progressions, minor progressions help astrologers observe several layers of inner development occurring at different speeds within the same life period.

Progressed Midpoints

Alongside the three progression systems, this report also calculates your progressed midpoints. A midpoint is the halfway point between two planets, and it tends to act as a sensitive spot in the chart. As your progressions move, a progressed planet can move onto one of these midpoints, bringing the blended meaning of the two planets into focus for that period. Progressed midpoints add a fine layer of timing to the broader progression cycles, pinpointing when a particular combination of energies becomes active. This is the progressed form of the technique. For midpoints in the natal chart and the 90 degree dial, see the Uranian astrology and midpoint report.

Emotional Archetypes in Progressions

Certain asteroids represent deeper emotional patterns within the natal chart. Bodies such as Chiron, Ceres, Psyche, Eros, and Black Moon Lilith describe themes connected with healing, nurture, instinct, desire, and psychological transformation.

This report examines how tertiary and minor progressions interact with these archetypal points. When a progressed planet forms a close aspect to one of these bodies, awareness of the emotional themes associated with that archetype may increase. These periods can correspond with moments of reflection, psychological insight, and emotional integration. The interaction between progressed planets and archetypal points helps reveal deeper layers of meaning within the unfolding life story.

What to Expect from Your Reading

Your progression charts reveal how the natal pattern evolves through time. The report helps you observe:

• Long cycles of personal development
• Changing emotional priorities
• Temporary phases of reflection and adjustment
• Deeper psychological themes activated by progressions

Together these systems show the movement of the inner life across different timescales.

This report can be used alongside your Transits & Progressions Report to add timing and context to your current life phase. You may also wish to explore the Solar Arc & Timeline Report for another symbolic timing method that highlights major turning points and longer-term shifts in direction.

Progression Timeline

In addition to generating your progression charts, this report also includes a Progression Timeline that helps you follow how important progressed changes unfold across time.

From the same report, you can explore each progression system individually by using the buttons at the top of the timeline. This allows you to switch between Secondary, Tertiary, and Minor Progressions and see how each timing method reveals a different layer of development.

Each timeline shows important progressed events such as aspects to natal planets, sign ingresses, and house ingresses. These can highlight periods of emotional change, psychological growth, inner turning points, and shifts in personal focus.

The timeline helps you observe:

• when progressed planets form important aspects to your natal chart
• when planets enter new signs or houses
• how longer and shorter progression cycles overlap
• how inner development unfolds across different life phases

Used together, the progression charts and timeline give a fuller picture of your evolving inner life. The chart shows the symbolic pattern for a chosen date, while the timeline helps you place that moment within a broader developmental cycle.
