Cadent House
The cadent houses are the 3rd, 6th, 9th and 12th — the four that fall away from the angles. A planet in one of them struggles to produce a result: things slip, delay, or never quite arrive.
The fuller picture
Cadent means falling, and the name is doing real work. These four houses come immediately after the succedent ones and immediately before the next angle, so a planet in one of them has just fallen away from the frame of the chart. It's the weakest of the three grades — one accidental point against three for a succedent house and five for an angular one — and the reading is that the planet can't easily deliver. A significator with every essential dignity going, made cadent, has no power to carry out what the chart has promised. That's worth stating the strong way round: essential dignity is capacity, and a cadent house is where capacity goes unused.
Two refinements matter more than the flat rule. The first is that the four aren't equally weak, though most accounts treat them as though they were. The third and the ninth do at least aspect the rising degree — the third by sextile, the ninth by trine — while the sixth and twelfth make no aspect to it at all. On that reasoning one modern traditional practitioner rates the third and ninth above the other two, and says plainly that this departs from common horary opinion. It's a judgement call rather than a correction, and our own engine doesn't make it: a significator in the ninth scores exactly as one in the twelfth. The second refinement is the planetary joys. A planet in its own house of joy gains comfort and familiarity there, which isn't the same thing as strength — and four of the seven joys fall in cadent houses, the Moon in the third, Mars in the sixth, the Sun in the ninth and Saturn in the twelfth. So Saturn in the twelfth is weak and at home at once, and one worked chart makes exactly that point about a quesited in the ninth — the house has little power to lend it, and lends it familiarity instead.
Timing is where cadency is most concrete, and where it produces the single most interesting cell in the whole system. The house grade sets the unit and the degrees between the two planets set the count; cadent is the slowest grade, so a cardinal sign in a cadent house gives months and a mutable sign years. And a fixed sign in a cadent house gives nothing at all. The tradition refuses the measurement outright — there is no unit to give from that cell, and in practice the blank usually means a very long wait. That refusal is invoked by name on a worked chart. Our own engine has no such outcome — it always returns a number, so on exactly those charts the app offers confident false precision, and we've got that logged as a correctness problem rather than a difference of opinion.
The third use of the grade is distance, and cadent is the far answer. In a question about where something is, or whether a person can be reached, cadent reads as a long way off and not easily got back — and a person that far out cannot be reached at all. It's the same fact producing a different reading because the question was different, which is the pattern for all three house grades.
One last caution, and it applies to the whole family of debilities. Cadency turns up constantly in the older topical rule lists as one item in a run — combust, or cadent, or peregrine, or retrograde — and lists built that way fire very easily. One of them fires on both of its own author's worked examples and points the wrong way both times. A cadent significator is a reason to look harder at the rest of the chart. It isn't an answer.
In your chart
Every planet's house is graded angular, succedent or cadent and scored into its accidental total, one point for cadent, and the grade is named in the dossier when you open a planet on the wheel. All four cadent houses score identically here, so the third and ninth are rated no higher than the sixth and twelfth — a refinement we've recorded and not adopted. The same grade sets the unit for the app's timing estimate, cadent being the slowest, and in a lost-object question it renders as far away or hard to reach, in an obscure or forgotten place. A planet in its joy is separately credited as a small positive, which is how the app distinguishes comfort from strength.
