Global Moon Phases & Lunar Intelligence System

What is a New Moon? The New Moon occurs when the Moon is positioned between the Earth and the Sun, making the lunar surface facing Earth completely dark. This marks the beginning of the lunar cycle and is often called the "dark moon" phase.

New Moon Characteristics:

• 0% illumination - the Moon is not visible from Earth
• Rises and sets with the Sun
• Best time for stargazing and deep-sky observation
• Occurs approximately every 29.5 days
• May cause solar eclipses when aligned perfectly

New Moon Significance: In many cultures, the New Moon represents new beginnings, fresh starts, and is considered an ideal time for setting intentions, starting new projects, and planting seeds. The New Moon calendar is essential for gardeners, fishermen, and those following lunar-based traditions.

New Moon Dates: Use our lunar calendar tool above to find all New Moon dates for any year. Track the next New Moon, upcoming New Moon schedule, and plan your activities around the monthly New Moon cycle.

What is a First Quarter Moon? The First Quarter Moon, also known as the Half Moon, occurs approximately one week after the New Moon. During this phase, exactly half of the Moon's visible surface is illuminated, appearing as a perfect semi-circle in the sky.

First Quarter Moon Characteristics:

• 50% illumination - right half visible in Northern Hemisphere
• Rises around noon and sets around midnight
• Best viewed in the evening sky
• Marks the midpoint between New Moon and Full Moon
• The Moon is waxing (growing) during this phase

First Quarter Moon Significance: The First Quarter represents a time of decision-making, taking action, and overcoming challenges. It symbolizes commitment and determination in lunar traditions. This is when the waxing crescent transitions into a more prominent half-moon shape.

Viewing the First Quarter: The First Quarter Moon is excellent for lunar observation as the terminator line (boundary between light and dark) reveals stunning crater details through telescopes. Check our moon phase calculator for First Quarter dates in your location.

What is a Full Moon? The Full Moon occurs when the Earth is positioned between the Sun and Moon, fully illuminating the lunar surface visible from Earth. This spectacular celestial event happens once each lunar cycle and has captivated humanity throughout history.

Full Moon Characteristics:

• 100% illumination - entire visible surface is lit
• Rises at sunset and sets at sunrise
• Visible all night long
• Can cause lunar eclipses during eclipse seasons
• Appears largest when near the horizon (Moon illusion)

Special Full Moons: Throughout the year, Full Moons receive special names based on Native American, Colonial American, and other cultural traditions:

• Supermoon: Full Moon at lunar perigee (closest to Earth)
• Blue Moon: Second Full Moon in a calendar month
• Blood Moon: Full Moon during a total lunar eclipse
• Harvest Moon: Full Moon closest to autumn equinox
• Wolf Moon, Snow Moon, Worm Moon: Traditional monthly names

Full Moon Calendar: Our global Full Moon calendar provides accurate Full Moon dates, times, and moonrise/moonset information for every country worldwide. Never miss a Full Moon again!

What is a Third Quarter Moon? The Third Quarter Moon, also called the Last Quarter Moon, occurs approximately three weeks after the New Moon. Like the First Quarter, half of the Moon's visible surface is illuminated, but now the opposite half is lit.

Third Quarter Moon Characteristics:

• 50% illumination - left half visible in Northern Hemisphere
• Rises around midnight and sets around noon
• Best viewed in the morning sky
• The Moon is waning (shrinking) during this phase
• Marks the transition toward the next New Moon

Third Quarter Moon Significance: The Third Quarter represents a time of release, reflection, and letting go. It symbolizes evaluation, forgiveness, and preparation for new cycles. In lunar gardening, this is considered a resting period.

Observing the Third Quarter: Early risers can enjoy the Third Quarter Moon in the pre-dawn and morning sky. The waning phase continues through the Waning Crescent until the next New Moon begins the cycle anew.

What is a Blood Moon? A Blood Moon is the popular term for a total lunar eclipse, one of the most spectacular celestial events visible from Earth. During a Blood Moon, the Moon takes on a striking reddish-copper or blood-red color as it passes through Earth's shadow. This phenomenon occurs when the Earth is positioned directly between the Sun and the Full Moon, blocking direct sunlight from reaching the lunar surface.

Why Does the Moon Turn Red? The Blood Moon's distinctive red color is caused by a phenomenon called Rayleigh scattering - the same process that creates red sunsets. As sunlight passes through Earth's atmosphere:

• Blue and green light wavelengths are scattered away
• Red and orange wavelengths pass through and bend around Earth
• This filtered reddish light illuminates the Moon during totality
• The exact color depends on atmospheric conditions (dust, pollution, volcanic ash)
• Colors can range from bright copper to dark blood-red

Types of Lunar Eclipses:

• Total Lunar Eclipse (Blood Moon): The Moon fully enters Earth's umbra (dark shadow), creating the famous red appearance. These are the most dramatic and occur 2-5 times per decade.
• Partial Lunar Eclipse: Only part of the Moon enters the umbra, creating a partial darkening effect without the full blood-red color.
• Penumbral Lunar Eclipse: The Moon passes through Earth's penumbra (lighter outer shadow), causing subtle darkening that's often difficult to observe.

Blood Moon Frequency and Visibility: Total lunar eclipses (Blood Moons) occur approximately 2-5 times per decade on average. Unlike solar eclipses, lunar eclipses are visible from anywhere on Earth where the Moon is above the horizon during the eclipse. This makes them much easier to observe without special equipment.

When is the Next Blood Moon? Use our Blood Moon tracker above to find upcoming lunar eclipse dates for any year from 2020-2035. Our data is sourced from NASA's eclipse predictions to ensure accuracy. Select your country to see local times and visibility information.

Blood Moon Cultural Significance: Throughout history, Blood Moons have held significant meaning in various cultures:

• Ancient civilizations viewed them as omens or divine messages
• The term "Blood Moon" has Biblical references in Joel 2:31 and Acts 2:20
• Many indigenous cultures have creation myths involving lunar eclipses
• Modern astronomy celebrates them as opportunities for scientific observation
• Photographers worldwide capture stunning Blood Moon images

How to Observe a Blood Moon: Blood Moons are safe to view with the naked eye - no special equipment needed! For the best experience:

• Check our eclipse calendar for exact timing in your location
• Find a location with a clear view of the sky
• The entire eclipse lasts several hours; totality typically 30-90 minutes
• Binoculars or a small telescope enhance the viewing experience
• Photography tip: Use a tripod and long exposure for best results
