Moon Phases

Quick answer (45 words): The Moon cycles through eight phases roughly every 29.5 days, from New Moon (invisible, beginnings) to Full Moon (illuminated, peak, release) and back again. Astrologically, each phase carries its own emotional weather and is widely used to time intentions, rituals, and emotional reset.

The eight phases at a glance

• New Moon — Invisible — Plant intentions, start fresh
• Waxing Crescent — Thin sliver — Build momentum, take first steps
• First Quarter — Half lit (right) — Push through resistance
• Waxing Gibbous — Mostly full — Refine, edit, prepare
• Full Moon — Fully illuminated — Peak energy, climax, release
• Waning Gibbous — Just past full — Gratitude, share, teach
• Last Quarter — Half lit (left) — Cut what's not working
• Waning Crescent — Thin sliver fading — Rest, reflect, surrender

The two big tentpoles are New Moon (set intentions) and Full Moon (release what no longer fits). Most people who track the Moon focus on these and let the in-between phases happen quietly.

Why the Moon's phase changes how you feel

The Moon doesn't actually emit light — it reflects the Sun. Astrologically, the angle between Sun and Moon (which is what creates the visible phase) is itself a constantly-changing aspect. At New Moon they sit conjunct (same sign, same degree). At Full Moon they sit opposite. Those are the two strongest aspects in the chart, which is why these days feel different.

Many people report sleeping less around the Full Moon. Studies on this are mixed, but the lived experience is consistent enough that even non-astrology people clock it.

How to actually use lunar phases

You don't need ritual tools. The simplest practice that holds up:

• New Moon: write down 3 intentions for the next month. Keep the paper.
• Full Moon (about 14 days later): re-read the paper. Note what shifted, what stalled, what you want to release.
• Last Quarter: cut one thing — a habit, a tab, a draft email — that's been draining the cycle.
• Waning Crescent: rest. Don't start anything new.

For couples: the New Moon in your shared 7th house (houses) is a strong day to have the conversation about what you both want this month from the relationship. See compatibility.

Moon phases, horoscopes, and tarot

Your monthly horoscope typically opens by naming the New and Full Moons of the month and the signs they fall in — that's the emotional skeleton of the month. A New Moon in your sign is an annual reset. A Full Moon in your sign is an annual climax.

In a tarot practice, the Moon card itself maps to the lunar cycle: it speaks to intuition, dreams, and what's hidden. Many readers do a "new moon spread" of three cards — what's seeded, what supports it, what gets in the way.
