Last quarter
The last quarter is the waning half-moon, seen about a week after the full moon. The Sun and Moon again form a right angle as viewed from Earth, and half of the visible disc appears lit, but the bright part is now shrinking toward the new moon. Tradition links this moment to review, sorting, and letting go of what no longer fits.
How to recognize it
At the last quarter, the other half of the disc glows, on the left in the northern hemisphere. This moon rises late, around the middle of the night, and stays visible in the morning, pale against the blue sky. If you are an early riser, this is often when you meet it above the horizon.
What the tradition invites you to do
The light is ebbing, and tradition sees this as a time to look back over what has happened since the full moon. You can take stock, finish what is lingering, tidy up, forgive, or set down what weighs on you. Nothing to force: take it as a gentle invitation to lighten the load, at your own pace, before the rest of the dark moon.
