The 4 Main Moon Phases Explained
The Moon doesn't change shape — we just see different amounts of its sunlit side as it orbits Earth. Over about 29.5 days it moves through four main phases:
● New Moon
The Moon sits between Earth and the Sun, so the side facing us is dark. It's the start of the cycle and the best time for stargazing because the sky is darkest.
◕ First Quarter
About a week later the right half of the Moon is lit (as seen from the northern hemisphere). It rises around midday and sets around midnight. This is a waxing phase, meaning the lit part is growing.
◯ Full Moon
Earth is between the Sun and Moon, so the whole face we see is lit. The full moon rises at sunset and is the brightest, most photographed phase. Each one has a traditional name (see the table below).
◖ Last Quarter
The left half is now lit and shrinking — a waning phase. The Moon rises around midnight and is high in the sky at dawn, before the cycle returns to a new moon.
🌕
Good to know: the in-between shapes have names too — a thin sliver is a crescent and a more-than-half shape is gibbous. On our calendars the symbols ● ◕ ◯ ◖ mark the four main phases on the day they occur.
Full Moons of 2027
2027 has 12 full moons.
Each full moon carries a traditional name from the Farmers' Almanac:
The names in the table — Wolf Moon, Snow Moon, Harvest Moon and the rest — come from Native American and colonial traditions collected by the Old Farmer's Almanac. Each name reflects what was happening in nature that month, like the Wolf Moon of deep winter or the Strawberry Moon of early summer. They're a fun, memorable way to track the year by the sky.
