About the Full Moon
At full moon the Moon is opposite the Sun in the sky, so its whole Earth-facing side is lit. It rises at sunset, is highest around midnight and sets at sunrise, staying up all night. The exact moment of fullness is a single instant, but the Moon looks full to the eye for about a day on either side.
A full moon is bright enough to cast shadows and to wash out all but the brightest stars, and lunar eclipses can only happen at this phase.
Lore and folklore
Every month's full moon carries a traditional name, from the Wolf Moon of January to the Cold Moon of December, drawn from Native American, colonial American and European traditions that tied each moon to the season.
Folklore linked the full moon to restlessness, sleeplessness and strange behaviour, which gave us the word lunacy. Festivals worldwide follow it: the Mid-Autumn Festival, Vesak, Holi and the date of Easter all depend on a full moon.
Trivia
- Full moons near the horizon look enormous, but photographs show they are the same size as overhead; the moon illusion is in the mind.
- The full moon is about 400,000 times fainter than the Sun.
- A full moon at perigee, a supermoon, is up to 14 percent wider than one at apogee.
- Because it is opposite the Sun, a winter full moon rides high while a summer full moon stays low.

This month's full moon: the Harvest Moon
The full moon closest to the September equinox, which can fall in September or early October.
Its name comes from the extra evening light it gave farmers finishing the harvest. Around the equinox the angle of the ecliptic to the horizon is shallow, so the moon rises soon after sunset for several nights in a row. It is the only full moon name defined by the equinox rather than the month.
Lore
For centuries farmers relied on the Harvest Moon's extra evening light to bring in the crops after sunset. The effect is real: near the equinox the Moon's path meets the horizon at a shallow angle, so it rises soon after sunset for several nights in a row. Harvest festivals across the northern hemisphere, from Canadian Thanksgiving to the Mid-Autumn Festival, sit close to this moon.
Trivia
- The Harvest Moon can fall in September or early October; it is the only full moon defined by the equinox rather than the month.
- 'Shine On, Harvest Moon' was a 1908 vaudeville hit that is still recorded today.
- The Mid-Autumn Festival is held on the day of this full moon in the Chinese lunar calendar.

How to read this moon calendar
Each day shows the Moon as it looks from Guaratinguetá at midday local time, with the illuminated percentage, moonrise and moonset. Days with a principal phase show the exact local time the phase occurs. Because the Moon moves about 50 minutes later each day, roughly once a month there is a date with no moonrise or no moonset at all.
From the southern hemisphere the Moon appears flipped: a waxing moon is lit on the left. The icons on this page follow that view.
The eight phases of the Moon
New Moon
The Moon sits between Earth and the Sun. Its lit side faces away from us, so it is invisible in the night sky. A new lunar month begins.
Waxing Crescent
A thin sliver grows each evening after sunset. Look low in the west shortly after dusk.
First Quarter
Half the disc is lit. The Moon rises around midday and sets around midnight, so it is high in the sky at sunset.
Waxing Gibbous
More than half lit and growing. It rises in the afternoon and shines most of the night.
Full Moon
The whole face is lit. It rises at sunset and sets at sunrise. Each full moon carries a traditional name.
Waning Gibbous
The lit portion shrinks. It rises after sunset and is still up in the morning sky.
Last Quarter
Half lit again, on the opposite side. It rises around midnight and is best seen in the early morning.
Waning Crescent
A thinning sliver before dawn in the east, fading toward the next new moon.
