Waning moon
The waning moon is the phase between the full moon and the new moon, during which the illuminated part of the moon becomes smaller from night to night. Astrologically, this phase is considered a time of letting go, integration and reflection.
What is the waning moon?
The waning moon describes the second half of the lunar cycle—from the full moon to the moon’s disappearance at the new moon. This phase can also be divided into sub-phases:
- Waning Gibbous: Immediately after the full moon — process insights, practice gratitude
- Last Quarter: Half moon, waning — letting go, tidying up, closing old chapters
- Waning Crescent (Balsam Moon): Shortly before the new moon — retreat, regeneration, inner stillness
Astrologically, the waning phase symbolizes dissolution, purification, and conscious letting go. What became visible during the full moon can now be sorted, processed, and—if necessary—released. This time invites us to slow down our pace and listen more deeply to our inner selves.
In practice, many people use the waning moon phase for detoxification, breaking unhealthy habits, or clearing out mental and physical clutter. Our article Changing Habits – Neuroscience offers a scientifically grounded perspective on habit change.
How can I tell if the moon is waxing or waning?
In the northern hemisphere, the mnemonic applies: If the moon is illuminated on the right (like a "D"), it is waxing. If it is illuminated on the left (like a "C" or "b"), it decreases. In the southern hemisphere, the opposite is true.
Is the declining phase suitable for new projects?
Rather not - astrologically, the waning phase is more suitable for conclusions and introspection. New ventures ideally start around the new moon or in the waxing moon.
