Grimoire

The moon doesn’t care whether you notice her. She’ll keep waxing and waning, pulling the tides, marking time in her ancient rhythm whether you’re paying attention or not. But when you do start paying attention, when you begin to align your intentions with her phases, something shifts. You stop fighting against natural rhythms and start flowing with them.

Each phase of the moon carries its own energy, its own invitation. Working with these phases isn’t about rigid rules or complicated ceremonies. It’s about recognizing where the moon is in her cycle and asking yourself: what does this energy support? What am I ready to plant, grow, release, or rest with?

Here’s how to work with each moon phase, complete with rituals you can adapt to your own practice.

New Moon ~ The Dark Beginning
Energy: New beginnings, intention-setting, planting seeds, rest, introspection, the void, potential

What’s Happening: The moon sits between Earth and the sun, invisible to us. This is the darkest night, the blank page, the moment before creation.

Long before we had smartphones buzzing with notifications and digital calendars syncing across devices, humans tracked time by watching the moon. The lunar cycle, that reliable 29.5-day journey from new moon to full and back again, provided our ancestors with a natural clock, a planting guide, and a sacred rhythm that shaped everything from festivals to fishing expeditions.

Even now, when we’re surrounded by artificial light and climate-controlled environments, something in us still responds to the moon. We feel the pull toward introspection during the dark moon, the surge of energy as she waxes full. Whether you’re setting intentions, making moon water, planning rituals, or simply trying to understand why you feel restless on certain nights, understanding the moon calendar can help you work with these natural rhythms instead of against them.

Understanding the Lunar Cycle
The moon doesn’t produce her own light, she reflects the sun’s. As she orbits Earth every 29.5 days, the angle of sunlight hitting her surface changes, creating the phases we observe from down here. This cycle, called a synodic or lunar month, has eight distinct phases:

On Sunday, December 21, 2025, at 10:03 AM EST, the Northern Hemisphere will experience the winter solstice. That’s the instant when the Sun reaches its southernmost point in the sky, marking the official beginning of astronomical winter and when daylight hours are at their minimum before they start lengthening again. Also known as the shortest day and longest night of the year. This astronomical event has captivated humanity for millennia, inspiring celebrations, rituals, and traditions that continue to resonate in our modern world.

What Is the Winter Solstice?
The winter solstice occurs when the northern half of the Earth is tilted its farthest away from the sun, causing the sun to reach its lowest point in the sky. While many think of it as an entire day, the solstice actually lasts just a moment. A precise astronomical alignment that marks the official beginning of winter.

The word “solstice” comes from the Latin words meaning “sun” and “still,” reflecting how the sun appears to pause in its southward journey before reversing direction. After December 21st, the days gradually begin to lengthen again, offering the promise of returning light and the eventual arrival of spring.

As we approach the winter solstice, the night sky gifts us with one last celestial spectacle of 2025. On December 19th at 6:43 PM MST, the final full moon of the year will rise, offering us a powerful opportunity for closure, reflection, and intention-setting as we prepare to welcome a new year.

The Cold Moon’s Significance
December’s full moon is traditionally known as the Cold Moon, named by Native American tribes for the long, frigid nights that accompany this time of year. It’s also called the Long Night Moon, as it occurs near the winter solstice when darkness reaches its peak in the Northern Hemisphere. This moon carries with it a particular energy of completion, rest, and inner contemplation.

A Moment of Cosmic Closure
There’s something profoundly symbolic about experiencing the year’s final full moon just days before the solstice and less than two weeks before the new year. This lunar event marks a natural pause point, a cosmic full stop that invites us to take stock of where we’ve been and where we’re heading.
