The eight Moon phases

The lunar cycle moves through eight commonly named phases from New Moon to Waning Crescent. Each phase describes a measurable Sun-Earth-Moon geometry and has also gathered symbolic meanings in calendars, rituals, and reflective practice.

These guides explain both layers. Use the astronomy for timing and the symbolism for optional reflection without treating the Moon as a guarantee of mood, fate, or outcome.

How a lunar cycle works

A synodic lunar cycle lasts about 29.5 days. The visible phase changes because the Moon's position relative to Earth and the Sun changes, revealing different portions of its illuminated half.

The eight names divide continuous motion into useful stages. Exact phase moments should be calculated in UTC and converted to the relevant local time zone.

Using Moon phases responsibly

A phase can create a memorable rhythm for planning, journaling, rest, or review. Its usefulness comes from consistent observation and action, not from claiming that the Moon forces an event.

Keep direct communication, material evidence, consent, health, safety, and qualified advice in view whenever a symbolic practice touches a consequential decision.
