Transits to a Davison relationship chart

A Davison chart is cast for the midpoint in time between two births and the midpoint in space between the two birthplaces, so it is a chart of a moment that really happened over a place on the map. That is what makes this page possible: a chart with a date and a horizon can be transited, exactly as a birth chart is. What you get here is one day of sky read against the chart of a relationship rather than against either person.

Cast the chart

This is not the same as a relationship forecast built on a composite chart, and the difference is worth knowing before you use either. A composite averages two charts point by point; it has no moment of its own, and its houses are equal divisions measured from a midpoint Ascendant. Transits to it are still read, but "Saturn is crossing the seventh" means less when the seventh is a construction. The Davison has an Ascendant and a Midheaven that belonged to a real sky over a real place, so a transit crossing them is crossing something.

The two charts also disagree about where the planets are, and both are right about their own question: an average of two positions is not the position at the average moment. So the composite forecast and this one are two readings of a couple, not the same reading twice. Where they agree, the case is stronger; where they differ, the Davison is usually nearer the timing and the composite nearer the feel.

Read the tightest contacts first. An aspect within a degree of exact is the loudest thing in the day, and the table here is ordered by orb for that reason. Then ask which planet is making it: the same aspect from Saturn and from the Moon are not the same event. A slow planet on a point of the relationship chart is a season the two of you are living through and will still be there next month; the Moon on the same point is an afternoon.

Houses matter as much as aspects here, which is the one place a Davison earns its keep over a composite. A planet walking through the seventh house of the relationship chart is working on the partnership as a partnership; through the fifth, on what the two of you enjoy together; through the fourth, on the home you make of it. This page lists every planet with the house it is passing through, even the ones aspecting nothing, because a transit through a house is doing something whether or not it touches a planet there.

Both birth times matter, for the usual reason. With both known the chart has genuine houses and angles and the report reads them. With one unknown the Davison is cast for noon on that side, the angles are guesses, and this page withholds the houses rather than printing ones it does not believe — you still get the aspects to the chart's planets, which is most of the day's weather.

A quiet day is a real answer. Some days nothing in the sky is within orb of the relationship chart, and the page says so instead of padding the table. Transits describe what a period is asking of two people; they do not decide anything, and a hard one is not a warning any more than an easy one is a promise.

Questions people ask

What are transits to a Davison chart?

The aspects today's planets make to the chart of a relationship, rather than to either partner's own chart. Because a Davison is a real moment over a real place, those aspects land on genuine houses and angles.

How is this different from a composite chart forecast?

A composite is an average of two charts with no sky of its own, and its houses are equal slices from a midpoint Ascendant. A Davison is a chart of a moment, so its houses and angles are real ones. The two also put the planets in different places, so they are two readings rather than one repeated.

Do we both need a known birth time?

For the aspects to the chart's planets, no. For the houses and the angles, yes — and those are the reason to transit a Davison rather than a composite, so with one time unknown this page shows the aspects and leaves the houses out.

Which transits matter most?

The tightest, and then the slowest. An aspect within a degree is the loudest thing in the day; a Saturn or Pluto contact is a season the pair are living through, while a Moon contact is that day and no more.

Nothing shows for today. Is something wrong?

No. Some days nothing is within orb of the chart, which is an ordinary quiet day rather than a fault. The houses the planets are passing through still say where the attention is.
