The Moon phase for January 7th, 2026 is a Waning Gibbous phase. This is the first phase after the Full Moon where the illumination of the moon decreases each day until it reaches 50% (the Last Quarter phase).

The waning (shrinking) gibbous Moon will rise after sunset in the east, transit the meridian after midnight, before setting after sunrise in the west.

During this phase, the illumination of the moon will go down from 99.% to 50.1%. Technically, the phase starts as soon as the Full Moon has passed, but it can be difficult to calculate and differentiate the first stage of a Waning Gibbous Moon from a Full Moon when 98-99% of the Moon’s surface is illuminated.

The Moon phase for January 4th, 2026 is a Waxing Gibbous phase. This is the phase where the moon is more than 50% illuminated but has not yet reached 100% illumination (which would be a Full Moon).

In the Northern Hemisphere, the right side will be illuminated, and in the Southern hemisphere it’ll be the left side that is illuminated.

The Waxing Gibbous phase, like all moon phases, will last for just over 7 days. The actual length will vary because of the elliptical shaped orbit of the moon. During this Waxing Gibbous phase the moon will rise in the east in the mid- to late-afternoon and will be high in the eastern sky at sunset.

Assuming it’s a clear night, the Waxing Gibbous moon will then be visible through most of the night before setting just before sunrise.

The Moon phase for January 3rd, 2026 is the Full Moon phase. In this phase, the moon is 100% illuminated when seen from Earth (hence the name Full Moon).

The Full Moon happens when the moon is on the opposite side of the Earth from the Sun. The sunlight fully illuminated the moon, and this is what we call being “full”. The moon will be visible throughout the night sky as it rises at sunset in the east, transits the meridian at midnight, before setting at sunrise in the west.

The specific point at which the Full Moon occurs can be measured down to a fraction of a second. The time that passes between full moons is called the Synodic month and is 29.530587981 days long.

The Moon phase for December 27th, 2025 is the First Quarter phase. In this phase, exactly half of the moon is illuminated and half is in darkness.

The First Quarter phase comes roughly 7 days after the New Moon and this is when the moon has completed one quarter of its orbit around the Earth (hence the name, First Quarter). The moon will be high overhead at sunset in this phase and will be visible until mid-night, when it sets in the west.

The First Quarter of the moon phase cycle happens on one day. It’s followed by the intermediate phase, Waxing Gibbous, and will become more illuminated every day until it reaches the Full Moon phase.

Assuming it’s a clear night, the Waxing Gibbous moon will then be visible through most of the night before setting just before sunrise.

The Moon phase for December 20th, 2025 is the New Moon phase. In this phase, the moon is positioned between the Sun and Earth and is 0% illuminated (i.e the moon is not visible to us in the sky).

Due to the alignment of the Sun, the Moon and Earth, the side of the moon that faces Earth is left in complete darkness. In technical terms this is referred to as a conjunction or Syzygy.

Also, during the New Moon phase, the moon rises and sets at around the same time as the Sun. This brings to the moon too close to the glare of the Sun for us to see the moon with the naked eye.

The Moon phase for December 18th, 2025 is a Waning Crescent phase. This is the phase where the moon is less than 50% illuminated but has not yet reached 0% illumination (which would be a New Moon).

In this part of the moon cycle, it is getting closer and closer to the Sun as viewed from Earth and the night side of the Moon is facing earth with a decreasingly thin crescent being illuminated.

The waning (shrinking) crescement Moon will rise at around midnight, transit the meridian after sunrise, before setting after noon. This phase is best viewed 1-2 hours before sunrise and is a great time to see the features of the Moon’s surface. Along the illuminated crescent you can see the craters and mountains of the moon casting long shadows.

The Moon phase for December 8th, 2025 is a Waning Gibbous phase. This is the first phase after the Full Moon where the illumination of the moon decreases each day until it reaches 50% (the Last Quarter phase).

The waning (shrinking) gibbous Moon will rise after sunset in the east, transit the meridian after midnight, before setting after sunrise in the west.

During this phase, the illumination of the moon will go down from 99.% to 50.1%. Technically, the phase starts as soon as the Full Moon has passed, but it can be difficult to calculate and differentiate the first stage of a Waning Gibbous Moon from a Full Moon when 98-99% of the Moon’s surface is illuminated.
