The 12 Houses in Your Birth Chart

How house cusps are calculated

A house cusp is the exact zodiac degree where one house ends and the next begins. Unlike the zodiac signs (which are fixed, always in the same 30-degree order), house cusps depend on your exact birth time and place: the same birth date at 6 AM and 6 PM produces a completely different set of house cusps, because the sky has rotated relative to the horizon. This calculator uses the Placidus system by default, the most common house system in modern Western astrology, and offers Whole Sign as an alternative. Both start counting from the same point (the Ascendant, which becomes the cusp of the 1st house) but divide the remaining eleven houses differently. The whole calculation, including your exact birth coordinates, runs locally in your browser; see the privacy page for exactly what that does and doesn't send anywhere.

1st house: self, appearance, first impressions

The 1st house cusp IS your Ascendant by definition, so this house is closely tied to how you come across when someone meets you for the first time, and how you instinctively approach new situations. A planet here tends to color your general presence strongly, almost like a second layer on top of your Sun sign.

2nd house: money, possessions, personal values

Traditionally linked to income, material possessions, and what you personally consider valuable (not just financially). A planet here often shapes your relationship with money, whether that's a steady saver's instinct, a more impulsive streak, or a strong attachment to security.

3rd house: communication, siblings, everyday learning

Covers how you think, talk, and process day-to-day information, along with relationships with siblings and close neighbors, and short trips. A planet here often shows up in how you write, speak, or absorb new information.

4th house: home, family, roots

One of the four angular houses (along with the 1st, 7th, and 10th), tied to home life, family background, and your sense of roots, sometimes described as the most private, foundational part of the chart. A planet here often shapes your relationship with your upbringing or your ideal version of "home."

5th house: creativity, romance, self-expression

Covers creative projects, romance (especially the playful, early-stage kind rather than long-term partnership, which belongs to the 7th), children, and anything done purely for enjoyment. A planet here often points to where you naturally like to perform, create, or take a lighthearted risk.

6th house: daily routine, work habits, health

Covers the practical, repeated parts of life: work habits, daily routines, and physical health and self-care. A planet here tends to show up in how organized or how flexible your everyday routine is, and how you approach the unglamorous, maintenance side of life.

7th house: partnerships, marriage, close relationships

The house directly opposite the 1st, covering committed one-on-one relationships: marriage, business partnerships, and close collaborations. Where the 1st house is about you alone, the 7th is about you in relation to another specific person. A planet here often colors what you look for in a partner, or how you show up inside a committed relationship.

8th house: shared resources, transformation, intimacy

Covers shared finances (joint accounts, inheritance, debt), deep intimacy, and transformation or change more broadly. Often considered one of the more intense houses. A planet here can point to a deep capacity for closeness, and sometimes to areas of life that go through significant, sometimes uncomfortable, change.

9th house: travel, higher education, beliefs

Covers long-distance travel, higher education, and the belief systems (philosophical, religious, or otherwise) you build your worldview on. A planet here often points to a hunger for bigger-picture thinking, whether that's through literal travel, formal study, or simply seeking out new perspectives.

10th house: career, reputation, life direction

The house cusp here IS your Midheaven, the second of the chart's two most personal angles (alongside the Ascendant). Covers public reputation, career, and overall life direction, essentially how the world sees your achievements. A planet here often shows up prominently in career or public-facing choices.

11th house: friendships, communities, long-term goals

Covers friend groups, communities, and long-term goals and hopes, distinct from the 7th house's one-on-one partnerships. A planet here often shapes the kind of groups you gravitate toward and how you pursue bigger, longer-range ambitions.

12th house: rest, the subconscious, things done privately

The final house, often linked to rest, the subconscious, and anything done alone, quietly, or behind the scenes, sometimes including endings and letting go before a new cycle (the 1st house) begins again. A planet here often plays out in a more internal, less publicly visible way than the same planet would in a more outward-facing house.

Quick reference table

Once you've calculated your own chart on the birth chart calculator, use this table to look up any house at a glance.

Angular houses (1st, 4th, 7th, 10th) are traditionally considered the most prominent: a planet in one of these tends to stand out strongly in a chart. Succedent houses (2nd, 5th, 8th, 11th) build on what the angular houses start, and cadent houses (3rd, 6th, 9th, 12th) are traditionally read as more adaptable or transitional.
