Planets, signs and houses answer different questions
In astrological tradition, a planet names a symbolic function, such as Mercury for communication. Its sign describes a style; its house places the theme in a life area. These are interpretation tools, not measured personality traits. The twelve sections below are a reference guide, not a reading of your own chart.
A sign is not a house
Aries does not automatically mean the first house, and a Pisces Sun does not establish a twelfth-house placement. A chart combines a zodiac, calculated positions and a house system. Knowing only a Sun sign cannot tell you where the planets fall by house.
1 · Self and first impressions
Beginning, presence and how you meet a situation. Notice how you introduce yourself to a new group.
2 · Personal resources
Possessions, priorities and what you value. Compare one purchase that felt useful with one that did not.
3 · Everyday communication
Conversation, nearby surroundings and ordinary learning. Consider whether writing or speaking helps you explain an idea.
4 · Home and roots
Home, family history and a sense of belonging. Name one small change that would make your space feel more restful.
5 · Play and expression
Creativity, enjoyment and romance. Try a hobby for the pleasure of making something, without needing to impress.
6 · Daily routines
Everyday work, service and habits of care. Explore which part of a busy morning could become easier.
7 · One-to-one relationships
Partnerships and explicit agreements. Ask a friend how each of you prefers to handle a changed plan.
8 · Shared resources and trust
Joint commitments, boundaries and change. Discuss how to divide a shared expense before assuming agreement.
9 · Wider perspectives
Beliefs, travel and extended study. Choose a question you would like to explore beyond your usual sources.
10 · Public roles
Vocation, responsibility and reputation. Describe the contribution you want others to recognize in your work.
11 · Groups and shared hopes
Friendships, communities and collective projects. Notice which group makes room for your actual interests.
12 · Quiet and private experience
Solitude, endings and experiences that are hard to put into words. Ask what helps you rest after a demanding day.
Whole Sign and Placidus can give different house placements
Whole Sign assigns the entire rising sign to house one, then counts signs in order. Placidus uses a time-based division tied to the birth location; house sizes can differ, with limitations near polar latitudes. Switching systems can move a planet between houses while leaving its sign unchanged. Neither setting is a scientifically validated personality test.
An invented example: the same Moon sign, different life areas
Imagine two fictional charts with Moon in Taurus. In house four, a symbolic reading might explore familiar surroundings; in house eleven, belonging within a group. The sign stays the same while the area changes. These invented placements describe neither you nor another real person.
An empty house does not mean a missing opportunity
A house without a planet is not a verdict on love, work or family. Astrologers may look at its sign and ruler, but none of this guarantees events. Use the topics as questions, not a reason to fear an empty sector.
Without a reliable birth time, leave personal houses unknown
House placement needs a reliable birth instant, birthplace and a chosen system. Do not substitute noon or your current time zone for missing birth information. Selfetti uses tropical Whole Sign houses when those details and a usable Ascendant are available. With an unknown birth time, it shows possible planetary signs and leaves personal houses unassigned.
Check these settings before comparing charts
- The same birth date and a recorded, rather than guessed, local birth time.
- The same birthplace and historical time zone, including daylight saving where relevant.
- The same zodiac: Selfetti uses the tropical zodiac, not astronomical constellation boundaries.
- The same house system. Keep the exact Ascendant point distinct from a house boundary; Whole Sign starts at the beginning of the rising sign.
- Uncertain inputs stay uncertain. Use Selfetti’s calculator for Whole Sign houses only with a reliable birth time and birthplace. If either is unknown, compare planetary signs without guessing personal houses.
Questions about houses
Does Selfetti calculate my twelve houses?
Yes, with a reliable birth time, birthplace and a usable Ascendant. The calculator gives twelve Whole Sign house cusps and the house of each of the ten planets in the tropical zodiac. It does not calculate Placidus; unknown birth time means no personal houses.
Can a house tell me whether a relationship or career will succeed?
No house placement establishes another person’s feelings or a future result. Real choices, agreements and circumstances still matter.
