This free tool compares both progressions using the 365.25-day key. Allow up to three minutes; you can cancel while it runs. Incomplete runs show no result.

Calculation method and limits

Houses use each progressed ephemeris date at its natal place. Both people share the same resolved target instant. The site caps this operation at 4 provider requests and approximately 140 internal service credits if both natal charts need calculation. Visitors are not charged.

What this result helps you understand

Exact relationship-chapter timing page that compares both people's secondary progressions on one shared target date.

These calculators turn exact two-chart comparison into a more trustworthy relationship read. They are built for users who have moved past beginner compatibility pages and need cleaner emotional, attraction, and communication context.

Guide

How compatibility is evaluated

Compatibility is strongest when one quick score is supported by emotional fit, communication rhythm, attraction style, and long-term context.

What is compared

Sign tools compare selected signs. Exact tools compare two birth charts. Kundli matching should verify Nakshatra, Guna Milan, Manglik context, and timing.

Score logic

The score is a high-level summary of ease and friction. Read it together with the notes, placements, and relationship themes beneath it.

Depth

Moon, Venus, Mars, synastry, and complete Kundli context add depth when the relationship question needs more than one matching layer.

Emotional compatibility

Moon signs, Moon aspects, Nakshatra context, and daily care patterns show how safe and understood the bond may feel.

Communication

Mercury, element balance, pacing, conflict style, and repair habits matter more than a single attraction score.

Attraction

Venus, Mars, chemistry indicators, and mutual responsiveness describe desire more clearly than Sun signs alone.

Long-term potential

Shared values, seventh-house themes, timing cycles, family expectations, and real behavior keep the reading practical.

Guide

Deeper guide to this calculator

Use this section before and after the result: first to understand what the tool measures, then to interpret the answer with context.

What it does

This is the general two-person progression read: it compares each person's progressed chart with their own birth chart on one shared date, with no commitment or repair framing. Start here to see the broader chapter you are both in; the marriage and reconciliation pages run the same comparison under a narrower lens.

Input required

Birth date, exact time and place for both people, plus one target date, time and city for the shared time zone. Birth times matter most, since they fix each progressed Ascendant; the target clock time changes very little.

How it works

Each chart is advanced one day per year of life on a 365.25-day key, and the progressed Sun, Moon, Mercury, Venus, Mars, Saturn and Ascendant are checked against the natal versions of those points. Every match is counted, the eight closest per person are listed, and one line reports the midpoint composite chart's major aspects.

How to interpret the result

Separate fast and slow factors: progressed Moon contacts change within months, while progressed Sun contacts can last a decade. In a constructed example, Person A shows progressed Sun sextile natal Mars at 2.40 degrees; a year later that orb has shifted by only about one degree, while most of A's progressed Moon contacts have changed, because the progressed Moon covers about twelve to thirteen degrees a year. Contacts that persist across both runs describe the long background.

Why it matters

Secondary progressions are a main symbolic timing technique in modern Western astrology, and reading two people's together shows that partners grow on separate timetables. This general page is the place to start when no specific event is in mind.

Traditional meaning

Astrologers describe the progressed Moon as the emotional chapter, about two to two and a half years per sign, and the progressed Sun as a slow shift in identity and purpose. Sharply different chapters are read as two people developing in parallel, not as a mismatch.

Reflection use

Run the tool for today and for one year from today, then circle the contacts that appear both times for each person. Talk together about the longer themes you each recognize, treating them as conversation starters rather than labels.

Beginner mistakes to avoid

Reading one person's list as if it described the other, when each list measures a chart against itself.
Treating a busy list for one partner and a quiet one for the other as the pair being out of step.
Running only one date and never learning which contacts are long background and which are brief.

Limits to keep in mind

It never compares the two progressed charts with each other; there is no progressed synastry here, and no date range is searched.
Behavior and mutual care matter more than any chapter shown here, and anyone feeling unsafe should reach out to someone they trust or a local support service.
