Free Hayz & Halb Calculator

Hayz (from an Arabic word for a planet's own domain or precinct) is the strongest sect condition a traditional planet can hold. A planet is in its hayz when it keeps to the sect of the chart in three ways at once: it is of the sect in favor, it stands in the hemisphere proper to its sect, and it sits in a sign of its own gender. William Lilly called it "a great fortitude." A planet in hayz tends to act with ease and on its own terms.

Hayz builds directly on sect, the day or night character of the whole chart. The guide to sect in astrology covers that chart-level picture: which light leads, and which planets belong to the team in favor. This calculator takes the next step and asks the question planet by planet, so you can see how settled each one is inside the sect rather than only whether it is on the right side of it.

The calculator checks three conditions for each planet and names the ones that hold. Halb is the middle of the three, not a separate technique: a planet in its halb has the first two conditions, and it reaches full hayz when it adds the third.

1. Sect. The diurnal team is the Sun, Jupiter, and Saturn; the nocturnal team is the Moon, Venus, and Mars. A diurnal planet is of the sect in a day chart, a nocturnal planet in a night chart. Mercury joins whichever team its solar phase puts it on: diurnal as a morning star, nocturnal as an evening star.
2. Halb (hemisphere). Halb means "half," the day half or night half of the chart. A diurnal planet keeps its halb above the horizon (the six houses from the Descendant up to the Ascendant); a nocturnal planet keeps it below. This is the condition that needs an accurate birth time, since it depends on the houses.
3. Gender. A masculine planet in a masculine sign (fire or air), or a feminine planet in a feminine sign (earth or water). The gender is the planet's own, which is why Mars, masculine but nocturnal, takes its match from a masculine sign while still following the nocturnal rule for sect and hemisphere.

Meet all three and the planet is in its hayz. Meet the first two and it holds its halb, one step short. Keep only the sect, with the hemisphere out of place, and the planet is of the sect without the settled comfort. Belong to the opposite team and it is contrary to sect.

Each planet gets one of four verdicts, strongest first: in hayz, in halb, of the sect, or contrary to sect. The sect light is worth reading first, since a Sun in hayz by day or a Moon in hayz by night is one of the clearest signs of a chart at home in its own sect. The calculator marks the sect light so you can find it at a glance.

A contrary planet is not a problem to fix, only a planet working against the grain of the time. The contrary malefic, Mars by day or Saturn by night, is the one the tradition watches most closely; the benefic and malefic calculator sorts those roles for the chart as a whole. Read each planet's hayz alongside its essential dignity, its house, and its aspects rather than as a verdict on its own.

These conditions sit close together, so here is where each one lives. Sect is the chart-level frame: day or night, sect light, and the team in favor. Hayz takes that frame down to the single planet and grades how fully it keeps to it. The two answer different sizes of the same question, which is why it helps to run sect first and hayz second.

Hayz is also distinct from a planet's joy (the house it rejoices in) and from essential dignity (rulership, exaltation, triplicity, bound, and face). A planet can be in hayz without being dignified by sign, and dignified without being in hayz. For the question of whether a planet is being actively helped or harmed by the benefics and malefics around it, that is bonification and maltreatment, and for the sect light's bodyguards, the doryphory calculator. Hayz answers only one thing, and answers it cleanly: how at home is this planet in the sect of the chart.
