12th house synastry overlay
12th house synastry puts their planet in your 12th house: they touch what you do not have words for, which is why this overlay gets called karmic.

How a 12th house overlay feels
The twelfth house is hidden, private and unconscious, so overlays here work below the surface. The planet person often touches the house person's fears, dreams, secrets or spiritual life, and the connection can feel fated or hard to explain. These overlays are associated with deep compassion and healing — and with secret relationships, confusion and self-sacrifice. The house person often feels the other sees a part of them they rarely show.

House person and planet person
Who feels a 12th house synastry overlay more?
The 12th house overlay is the most debated. Traditionally the house person feels it more, and often without words: the planet person touches what they hide or have not faced, which can feel healing, haunting or confusing. The planet person may feel a strong but unexplained pull and, at times, unseen — they are acting on a part of the other person that is not on show.
By rising sign
Whose Sun lands in your 12th house
With whole-sign houses your 12th house is the sign 11 steps on from your rising sign. A partner born while the Sun was in that sign has their Sun in your 12th house; their other planets need their own chart.
| Your rising sign | Your 12th house | Partner’s Sun there if born |
|---|---|---|
| Aries rising | Pisces | February 19 – March 20 |
| Taurus rising | Aries | March 21 – April 19 |
| Gemini rising | Taurus | April 20 – May 20 |
| Cancer rising | Gemini | May 21 – June 20 |
| Leo rising | Cancer | June 21 – July 22 |
| Virgo rising | Leo | July 23 – August 22 |
| Libra rising | Virgo | August 23 – September 22 |
| Scorpio rising | Libra | September 23 – October 22 |
| Sagittarius rising | Scorpio | October 23 – November 21 |
| Capricorn rising | Sagittarius | November 22 – December 21 |
| Aquarius rising | Capricorn | December 22 – January 19 |
| Pisces rising | Aquarius | January 20 – February 18 |
Sun-sign dates shift by a day in some years. Equal and Placidus houses can give a different answer near a cusp; the synastry calculator places every planet of both charts.

6 —
routine, work and health
House type
cadent
This house pairs with the 6th across the chart — routine, work and health — and the two work as one axis. A planet landing here looks straight across at that house, so the two readings belong together rather than separately.
It is a cadent house, which precedes an angle and is the group traditionally read as adjustment and transition. Its natural ruler is Neptune, so a partner's Neptune arriving here doubles the theme rather than adding a new one.
The 12–6 axis
What is hidden, dissolved or carried unconsciously sits opposite routine, work and health. A planet in one faces the other across the chart, so an overlay here is always a statement about both — they touch what you do not have words for, which is why this overlay gets called karmic; at the 6th-house end, you meet in the ordinary: shared tasks, schedules, looking after things.
