The two teams, and the planet that switches
Sect divides the planets into a day team and a night team. The day team is the Sun, Jupiter and Saturn; the night team is the Moon, Venus and Mars. Mercury has no side of its own. Its team depends on its position relative to the Sun.
A chart is a day chart when the Sun is above the horizon and a night chart when the Sun is below. In a day chart the Sun leads the team, in a night chart the Moon does. This is the starting point for almost every other traditional technique, because it decides which planets are working with the chart and which are working against it.

The Book of the Sky
How people learned to read the sky, from Babylon to the day you were born.
Why Saturn is easier by day and Mars easier by night
The two malefics land on opposite teams: Saturn is a day planet and Mars a night planet. In the traditional teaching the malefic that belongs to the chart's own team is the milder one, so Saturn is easier in a day chart and Mars in a night chart, while the malefic of the other team is the harder one. The two benefics follow the same pattern, with Jupiter at its best by day and Venus at its best by night.
Dorotheus has a line that cuts the other way. In his Book I (chapter 6) he says Saturn harms those born by day and Mars those born at night, the reverse of the usual rule, although elsewhere (I.27) he gives Saturn the day and Mars the night as their portions. The authorities were not unanimous, so when a source contradicts the common doctrine, check which author is speaking.
Halb, hayyiz and the bodyguard rule
The medieval astrologers added a position test on top of the team list. A planet is in its halb, or portion, when a day planet stands above the horizon in a day chart or below it in a night chart, or when a night planet stands below the horizon in a day chart or above it in a night chart. Al-Qabisi describes such a planet as a man in a place of his own benefits.
Hayyiz is halb plus one more condition, that the planet stands in a sign of its own gender. Bonatti uses the word in four different senses, partly because of a copyist's error in an Arabic copy of al-Qabisi, so a modern reader should check which meaning an author intends.
The third idea is doryphoria, the bodyguard. A planet acts as an escort to a luminary: a planet in its hayyiz on the eastern side of the Sun by day, or the western side of the Moon by night. Bonatti uses it to judge the eminence of a parent, looking at the Sun with eastern day planets for the father in a day chart and at the Moon with night planets for the mother.
What to do with sect in a chart
Four steps cover most practical readings:
- Decide whether the chart is a day chart or a night chart from the Sun's position.
- Mark the benefic and malefic of the chart's own team, who are the helpful one and the milder difficult one.
- Check whether any planet is in its halb (right side of the horizon for its team).
- When two readings of a planet compete, prefer the one that matches the sect.
Firmicus adds a Moon rule for night charts: a waning Moon met by waning Venus or Mars brings good fortune, while a waxing or full Moon joined to Venus or Mars brings great misfortune, because Venus is hostile to the growing Moon by a kind of natural envy. That is a sect rule in its early form, and it shows how old the habit of reading a planet by the hour of birth is.
Why Sect matters
Sect matters because it changes how traditional astrology weighs planets, especially the luminaries, Jupiter, Venus, Saturn, and Mars.
Where readings of Sect go wrong
A common error is to apply sect mechanically without checking whether the chart is truly diurnal or nocturnal.
