Reading the chart
The 12 houses in astrology
Houses divide a chart into areas associated with different life topics. Astriel defaults to Placidus, which calculates unequal houses from the birth time and location. Read each planet against the calculated cusp boundaries shown in your result.

Read a Placidus house from one cusp to the next
A cusp is the starting boundary of a house. In the result's house list, each boundary has a sign and degree. Move forward through the zodiac from that position to the next cusp: planets in that interval belong to the house.
- Find the starting cusp. In Placidus, house 1 begins at the Ascendant and house 10 at the Midheaven.
- Check the next cusp. Houses have unequal widths. Do not assume the next boundary is 30 degrees away or at a new sign.
- Place the planet between the boundaries. Compare its full zodiac position, including the sign. At the exact next cusp, Astriel assigns it to the next house.
For example, suppose house 1 starts at 20° Libra and house 2 at 15° Scorpio. A Sun at 10° Scorpio is still in house 1. The Sun's sign is Scorpio; the sign on the first-house cusp is Libra. Both facts belong in the reading.
Why signs can repeat or disappear from the cusp list
The twelve houses remain present even when two consecutive cusps share a sign. A wide house can also contain a whole sign without any cusp starting in it. That sign is called intercepted. Its planets still have signs and house placements; they have not disappeared from the chart.

Reading your house placements
Start with the house topic, then read any planets in it. The 2nd house concerns personal resources; Mercury there connects that topic with learning and exchange. Its sign and aspects add detail to the interpretation.
Follow the house ruler
Every house has a ruling planet, even when it contains no planets. In Placidus, use the sign on the house's starting cusp and look up its traditional ruler. The ruler's placement connects that house topic to another area of the chart.
Worked example · Placidus cusp ruler
Leo on an empty 2nd-house cusp
- Suppose the calculated 2nd cusp is in Leo. The 2nd house concerns personal resources.
- The Sun rules Leo. Find the Sun in the chart's positions table.
- Suppose the Sun is in Aries, in the 10th house. That connects the 2nd-house topic with public work and responsibility.
An astrologer could read this as a theme of building resources through a visible role. It doesn't establish someone's job, income or future success. The Sun's aspects can add competing themes.
An empty house means that none of the listed bodies occupies it. Its topics remain part of the chart. Use the same ruler method for occupied houses too.

When the birth time is uncertain
Astriel leaves out houses for approximate or unknown birth times. The available planetary signs and ranges remain in the result. An exact time can still produce unavailable houses when the Ascendant cannot be calculated at that latitude.
Why two calculators can give different houses
House systems put the boundaries in different places. A planet can keep the same sign and degree while changing house. Compare the selected system as well as the birth details.
For this illustration, the Ascendant is 20° Libra and the Sun is 10° Scorpio. The Sun's position stays fixed in all three diagrams. For the Placidus illustration, suppose the second cusp is 15° Scorpio; a real chart needs its own calculated cusps.
- Placidus: Sun in house 1
- House 1 starts at 20° Libra and ends at the illustrative second cusp, 15° Scorpio. The Sun at 10° Scorpio comes before that boundary.
- Whole Sign: Sun in house 2
- House 1 starts at 0° Libra. House 2 begins at 0° Scorpio, before the Sun at 10° Scorpio.
- Equal House: Sun in house 1
- House 1 starts at the Ascendant, 20° Libra. House 2 starts 30° later, at 20° Scorpio. The Sun is still inside house 1.
Astriel defaults to Placidus and also offers Whole Sign. Equal House is an illustration here, not a calculator option. Changing the system changes house boundaries; it does not move the planets through the zodiac.
If calculators disagree on the Ascendant or planetary degrees too, check the local birth time, birthplace and time-zone conversion. Also compare the zodiac setting: tropical and sidereal positions use different reference points.
