December 12, 2025: Moon Enters Waning Crescent Phase With 50% Illumination, Next Full Moon to Rise January 3

On December 12, 2025, the Moon transitions from its last quarter phase in Virgo to a waning crescent, with just 50% illumination. Astronomers and skywatchers alike now look ahead to the next major event: the Wolf Moon, January 3, 2026.

If you look up tonight, December 12, 2025, you’ll spot the Moon slipping into its waning crescent phase. This marks a notable point in the lunar cycle, signaling the stretch toward a New Moon and effectively wrapping up another rhythm of our night sky’s regular dance.

From Last Quarter to Waning Crescent

Just hours ago, the Moon was basking in its last quarter phase in the astrological sign of Virgo — an earthy sign known for order and organization. At that stage, our lunar neighbor was about 22.02 days old, which means it had been nearly three weeks since the last New Moon. With roughly 50% of its surface still catching sunlight, the Moon appeared distinctly half-lit to observers. But as it shifts further into the waning crescent on December 12, its illuminated portion will steadily shrink, prepping for the New Moon that resets the cycle all over again.

The lunar cycle unfolds in a unique pattern every year, gifting skywatchers with fresh views and energies each month. Astronomers note that this seventh phase, the last quarter, sits tidily between the waning gibbous and the waning crescent. It’s short-lived but striking: only the right (or left, depending on where you live) half of the Moon is visible, hanging like a bisected silver coin in the night sky.

What’s Next? Anticipating the Wolf Moon

Those keeping tabs on celestial events won’t have to wait long for the Moon’s next big showcase. Mark your calendars for January 3, 2026, when the Wolf Moon — the year’s first full moon — will rise, ushering in both a new lunar cycle and, for many cultures, a host of new beginnings. The lunar calendar for next year is already packed, with Full Moons slotting in almost like clockwork: February 12, March 14, April 12, and so on.

For many, the Moon is more than a scientific marvel. Its ancient rhythm sets the pace for everything from gardening to spiritual practices. In fact, this waning crescent phase is said to be a time of deep introspection and letting go, as energy begins to retreat inward. Astrologers are already sharing affirmations and manifestation tips, encouraging folks to “restore energy by releasing over-effort” and allow themselves a break from constant productivity.

One thing’s for sure: Whether it’s a supermoon or an ordinary phase, the Moon never fails to intrigue — offering a reliable celestial companion as the year winds down and another lunar cycle waits just around the corner.
