Today’s Moon Phase
Moon Phases: October 16, 2026 – October 20, 2026 Moon Phases: October 17, 2026 – October 19, 2026
Today’s First Quarter Moon
The First Quarter phase occurs when half of the Moon's visible surface is illuminated. It follows the Waxing Crescent and marks the midpoint between the New Moon and the Full Moon. During this phase, the Moon appears as a half circle. The term "quarter" refers to the Moon having completed approximately one-quarter of its orbit around Earth.
This phase is most visible from early evening to midnight. On this date, the Moon appears in the southern sky after sunset and remains visible until it sets. The graph below provides key details about the Moon's position, including its altitude (height above the horizon), azimuth (direction), and the Sun's altitude. Use this information to understand the Moon's movement and plan your observations more effectively.
All times are in local time (UTC-04:00). They take into account refraction. Times reflect Daylight Saving Time (DST) where applicable. In certain polar regions (the Arctic and Antarctic), the Moon or the Sun may not rise or set.
First Quarter Moon in Detail
The appearance of this phase varies with hemisphere, particularly in how the illuminated portion is oriented. However, its basic features—such as illumination, timing, and cultural meaning—remain largely consistent. The following sections provide detailed information about its appearance, position in the lunar cycle, cultural significance, and visibility.
Key Features of the First Quarter Moon
Appearance: The First Quarter Moon appears as a half-lit circle, with the right side illuminated for observers in the Northern Hemisphere and the left side illuminated in the Southern Hemisphere. The terminator—the line between shadow and light—is sharp and straight, dividing the Moon cleanly in two. Illumination during this phase is approximately 50%.
Position in the Lunar Cycle: This phase follows the Waxing Crescent and precedes the Waxing Gibbous. It occurs about 7 to 8 days after the New Moon, marking the quarter point in the lunar month. It signals a shift toward the Full Moon, as the visible surface of the Moon continues to increase in brightness.
Symbolism and Cultural Significance: The First Quarter Moon represents decision-making, action, and growth. It is often seen as a time to confront challenges, take initiative, and move forward with goals or intentions set during the New Moon. Across cultures, this phase symbolizes progress through effort and commitment.
Visibility: This phase is best observed during the late afternoon and evening. It rises around midday, reaches its highest point at sunset, and sets around midnight. Its distinct half-moon shape makes it one of the easiest phases to recognize, and it remains clearly visible for several nights around the exact quarter phase.

Frequently Asked Questions
Why does the Moon look different every day?
The Moon looks different each day because it goes through phases as it orbits Earth. These phases occur because of the changing positions of the Moon, Earth, and the Sun. As their alignment shifts, different parts of the Moon’s illuminated side are visible from Earth. This creates the phases, such as New Moon, First Quarter, Full Moon, and Last Quarter.
What are the phases of the Moon?
The eight phases of the Moon, in order, are New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.
How long does it take for the Moon to complete a full cycle?
The Moon takes approximately 29.5 days to complete a full cycle, known as a lunar month or a synodic month. This is the time it takes to move through all eight phases, from New Moon back to New Moon, as seen from Earth.
How can I check the Moon phase for my location?
Our website already provides the moon phase specific to your location. It automatically detects your location to provide accurate moon phase information, including moonrise and moonset times.
Do Moon phases affect sleep or emotions?
Some studies suggest that moon phases, like the Full Moon, may slightly affect sleep, such as taking longer to fall asleep. However, there is limited scientific evidence linking moon phases to emotions. Cultural beliefs and individual perceptions may also contribute to these experiences.
