FAQ
Frequently Asked Questions
Not exactly. 'Waning moon' describes the process of decreasing illumination. A 'crescent moon' is a shape (a thin curve). A waning moon can be a crescent shape, but also a larger 'gibbous' shape as it shrinks from full.
It's quite formal or descriptive. In everyday talk, people are more likely to say 'the moon is getting smaller' or refer to a 'crescent moon'.
The opposite is a 'waxing moon', which is when the moon's visible illuminated area is increasing.
It is a powerful metaphor for decline, ending, loss, melancholy, or the passage of time, drawing on a universal natural cycle.
