The waning crescent is a phase of the lunar cycle that occurs after the last quarter moon and before the new moon. During this phase, less than half of the moon's surface is illuminated by the sun, creating a crescent shape that appears to shrink each night. The waning crescent is visible in the early morning sky, just before sunrise. This phase is part of the lunar cycle, which lasts about 29.5 days. The waning crescent signifies a time of reflection and preparation for the new moon, when the moon will be completely dark. It is often associated with letting go and setting intentions for the upcoming cycle.
