The Moon itself produces no light of its own. The length of the cycle can vary slightly, but on average, it is The primary phases occur at a specific moment, no matter where you are on Earth, which is then converted to local time.
Depending on where you live, you may or may not be able to see the exact moment of a phase, in part because the Moon may not have risen yet in your area. The secondary phases, however, represent a span of time rather than a specific moment. This phase is named as such because it starts a new lunar cycle. But if we were to travel to the other side of the Moon, the part that faces the Sun, it would be totally illuminated.
These events are only visible from a small portion of Earth and require special eye protection to be viewed safely. Read more about solar eclipses here! The months of some calendars, such as the Chinese lunisolar calendar, begin at the time of the new or dark Moon. This phase occurs between the new Moon and first quarter phases. At the beginning of this stage, we see a thin, crescent-shape Moon, which, in the Northern Hemisphere, appears on the right side.
In the Southern Hemisphere, the same thing happens, only on the left side. Some lunar and lunisolar calendars, such as the Islamic or Hijri calendar, define the start of a month as when the Moon first becomes visible, which is usually a day or so after the new Moon, during its waxing crescent stage. In fact, both the first and last quarter phases are sometimes called a Half Moon. During a first quarter phase, the Moon is said to be at east quadrature, meaning that it is 90 degrees east of the Sun when viewed from Earth.
This phase occurs between the first quarter and full Moon and describes the Moon when it is more than half lit, but not yet fully. At the beginning of this stage in the Northern Hemisphere, we see the right half of the Moon illuminated plus a tiny fraction more extending into the left side. In the Southern Hemisphere, the same happens, only from left to right. Visualization and information about today's Moon phase.

What Phase is the Moon in? Today the Moon is Waxing Gibbous and its age is Phase: Waxing Gibbous Age: Apparent Diameter 1, Predicted magnitude of The Moon between January and December Azimuth: Max altitude: The moon is a sphere that travels once around Earth every It also takes about 27 days for the moon to rotate on its axis. So, the moon always shows us the same face; there is no single "dark side" of the moon. As the moon revolves around Earth, it is illuminated from varying angles by the sun — what we see when we look at the moon is reflected sunlight.
On average, the moon rises about 50 minutes later each day, which means sometimes it rises during daylight and other times at night.
At new moon, the moon is between Earth and the sun, so that the side of the moon facing toward us receives no direct sunlight, and is lit only by dim sunlight reflected from Earth. A few days later, as the moon moves around Earth, the side we can see gradually becomes more illuminated by direct sunlight. This thin sliver is called the waxing crescent. A week after the new moon, the moon is 90 degrees away from the sun in the sky and is half-illuminated from our point of view — what we call first quarter because it is about a quarter of the way around Earth.
A few days later, the area of illumination continues to increase. More than half of the moon's face appears to be getting sunlight. This phase is called a waxing gibbous moon. When the moon has moved degrees from its new moon position, the sun, Earth and the moon form a line. Next, the moon moves until more than half of its face appears to be getting sunlight, but the amount is decreasing.
This is the waning gibbous phase. Days later, the moon has moved another quarter of the way around Earth, to the third quarter position. The sun's light is now shining on the other half of the visible face of the moon.
Next, the moon moves into the waning crescent phase as less than half of its face appears to be getting sunlight, and the amount is decreasing. Finally, the moon moves back to its new moon starting position.
Usually the moon passes above or below the sun from our vantage point, but occasionally it passes right in front of the sun, and we get an eclipse of the sun. Each full moon is calculated to occur at an exact moment, which may or may not be near the time the moon rises where you are. In fact, the moon will often look roughly the same on two consecutive nights surrounding the full moon.
Lunar eclipses are inextricably tied to the full moon. When the moon is in its full phase, it is passing behind the Earth with respect the sun and can pass through Earth's shadow, creating a lunar eclipse. When the moon is fully inside the Earth's shadow, we see a total lunar eclipse.
