Moon forecast for this month
December 2026 is shaped by four key Moon phases. The new moon falls on day 9, the first quarter on day 17, the full moon on day 24, and the last quarter on day 1. During the first part of the month the lunar disk gains brightness, reaches its peak near the full moon and then gradually wanes.
In a broad astrological context, the month moves between Sagittarius and Capricorn. Use this calendar not as a prediction, but as a practical guide for sky watching, evening plans and understanding how bright the Moon will be on specific dates.
FAQ
What are Moon phases?▾
Moon phases are the visible changes in the illuminated part of the lunar disk as seen from Earth. They happen because the Moon changes position relative to Earth and the Sun.
What is the difference between new moon, full moon and quarters?▾
A new moon is when the illuminated side is almost invisible from Earth. A full moon is when the disk is brightest. The first and last quarters are intermediate phases.
What does the illumination percentage mean?▾
The illumination percentage shows how much of the visible lunar disk is lit by the Sun. The higher the value, the brighter the Moon appears at night.
How should I use the day-by-day moon calendar?▾
Use it to quickly check which Moon phase falls on a specific date, when the key phases occur and how bright the Moon will be on that night.
