The "Last Quarter" refers to a specific phase of the lunar cycle when the Moon appears as a half-circle in the sky. This phase occurs about three weeks after the New Moon and one week after the Full Moon. During the Last Quarter, the Moon is illuminated on the left side in the Northern Hemisphere, while it appears illuminated on the right side in the Southern Hemisphere. In this phase, the Moon rises around midnight and sets around noon. The Last Quarter is significant in various cultures and is often associated with reflection and letting go, making it a time for introspection and planning for new beginnings.
