Why the Moon changes shape
Sunlight always illuminates roughly half the Moon. From Earth we see different portions of that illuminated half as the Moon orbits. The ordinary phase cycle is not Earth's shadow moving over the Moon; that shadow is involved in a lunar eclipse.
The eight familiar phases
The cycle begins at new Moon, followed by waxing crescent, first quarter and waxing gibbous. Full Moon is followed by waning gibbous, last quarter and waning crescent. Waxing means the visible illuminated portion is growing; waning means it is shrinking. The cycle takes about 29.5 days.
Phase is different from sign
A Moon phase describes its relationship to the Sun as seen from Earth. A Moon sign describes its zodiac position. Two days with similar phases can place the Moon in different signs. Neither value supplies a personal natal chart or a complete forecast.
A reflective lunar practice
Some people use the new Moon to name an intention and the full Moon to review progress. This is a chosen ritual, not a requirement imposed by the sky. A useful version is simple: record an intention, observe what happens and revise it based on evidence.
Finding the current phase
This is an evergreen explanation rather than a live lunar calendar. Use a dated ephemeris or a current phase tool when you need the actual phase for a particular time. Exact event times may appear on different local dates depending on the time zone, so check the zone alongside the date.
