Every month has a New Moon and a Full Moon. Most of what's written about them is generic: "set intentions," "release what no longer serves." That's horoscope-column astrology, the same for everyone. The personal version is different: each lunation falls in one of your twelve houses, and the house tells you where in your life this month's beginning or culmination lands.
This guide covers the lunar cycle, what New and Full Moons do, how to find the house, what each house placement tends to mean, and the two amplifiers: a lunation on a natal planet, and a lunation that's also an eclipse.
The cycle in one paragraph
The Moon orbits the Earth in about 29.5 days relative to the Sun. When it's between us and the Sun, it's invisible: New Moon. Two weeks later it's opposite the Sun and fully lit: Full Moon. In between are the waxing (growing) half and the waning (shrinking) half. A New Moon is a Sun-Moon conjunction; a Full Moon is a Sun-Moon opposition. Both fall at a specific degree of the zodiac, and that degree lands somewhere in your chart.
New Moon: beginnings you can't see yet
A New Moon is a seed. Something starts, usually quietly, often below the level of notice. It's not a good time to see results; it's a good time to begin. The two weeks that follow, the waxing half, are for building on it.
In practice, the New Moon's effects are subtle. Most people don't feel a New Moon unless it hits a natal planet. Its value is in knowing where to look for the next beginning.
Full Moon: what comes into view
A Full Moon is a culmination. Something that was seeded two weeks earlier (or six months earlier, at the New Moon in the same sign) becomes visible. Emotions run higher; things get said; a situation reaches its peak or its breaking point.
Full Moons are felt. They're the ones people notice, usually as a day or two of heightened feeling, a revelation, or a resolution. The waning half after a Full Moon is for processing and releasing.
Finding the house
Take the degree of the lunation (say, 15 degrees Taurus) and find which of your houses contains that degree. If your 2nd house runs from 3 degrees Taurus to 1 degree Gemini, the lunation is in your 2nd house.
This needs a reasonable birth time. With no time, use whole sign houses from the Sun sign as a rough proxy, and hold the house reading loosely.
New Moon by house
Where a new beginning is seeded this month:
- 1st: yourself. A new habit, a new look, a fresh personal start.
- 2nd: money and values. A new income source, a spending reset.
- 3rd: communication, learning, siblings, the neighborhood. A new course, a new project of writing or talking.
- 4th: home and family. Moving, redecorating, a family matter opening.
- 5th: romance, creativity, children. A new attraction, a new creative project.
- 6th: work and health. A new routine, a new job task, a health regime.
- 7th: partnership. A new relationship, or a new phase in one.
- 8th: intimacy, shared money, transformation. A joint financial start, a deepening.
- 9th: travel, education, belief. A trip planned, a study begun.
- 10th: career. A new role, a new public direction.
- 11th: friends, groups, goals. A new community, a new long-term aim.
- 12th: the inner life. A quiet start, often something you won't recognize until later.
Full Moon by house
Where something comes to a head this month:
- 1st: you're seen; a personal matter comes to light. Often opposite the 7th: you versus a partner.
- 2nd: money matters resolve; a bill, a payment, a decision about what you value.
- 3rd: something gets said; a conversation that was coming.
- 4th: a family or home matter peaks. Often opposite the 10th: home versus career.
- 5th: a romance or creative project reaches a turning point.
- 6th: a work or health situation comes to a head.
- 7th: a relationship reaches clarity; commitment or ending.
- 8th: a shared finance or intimacy matter resolves.
- 9th: a belief tested, a journey completed, a course finished.
- 10th: public recognition or public exposure; a career matter peaks.
- 11th: a friendship or group matter culminates.
- 12th: something hidden surfaces; a private ending.
The Full Moon always involves two houses (the Moon's and the Sun's, opposite each other), so read the axis: 1st-7th is self versus partner, 4th-10th is home versus career, 2nd-8th is your money versus shared money, and so on.
Lunations on natal planets
A New or Full Moon within about 3 degrees of a natal planet activates that planet for the month. This is when lunations stop being subtle.
New Moon on natal Venus: a new relationship or creative beginning. Full Moon on natal Saturn: a responsibility comes due; something serious peaks. New Moon on natal Sun (which happens once a year near your birthday): a personal new year. Full Moon on natal Mars: anger or action reaches a head.
Lunations on the Ascendant or Midheaven are similarly loud: personal visibility, or public visibility.
If a lunation isn't on a natal planet or angle, it's usually a quiet month for that house. That's useful to know too.
When it's an eclipse
Twice a year, for about a month each time, the New and Full Moons fall near the lunar nodes and become eclipses. An eclipse is a lunation with the volume turned up: the beginning or culmination is bigger, lasts longer (effects unfold over months rather than weeks), and tends to bring events that feel fated.
An eclipse in a house marks that house for the next six months. An eclipse on a natal planet is a significant life event in that planet's domain, and one that usually gets a full guide of its own. The short version: read eclipses by house exactly as above, then multiply.
The quarter Moons
Halfway between New and Full is the First Quarter (a crisis of action: push through or give up). Halfway between Full and New is the Last Quarter (a crisis of consciousness: what did that mean, and what do I drop?). They're softer than the New and Full but useful for pacing a month: begin, push, see, release.
Track your lunations
Open the moon phase tool. It shows the current phase, the next New and Full Moon with dates and zodiac degrees, and the natal house each one falls in for your chart. For a longer view, the lunation analyzer lists the year's lunations and eclipses with their contacts to your natal planets.
The practical habit: at each New Moon, check the house and note one thing you'd like to begin there. At the Full Moon two weeks later, check the opposite house and notice what came into view. After three or four months the pattern is hard to miss.
