when does the moon begin to wane?
The moon begins to wane after reaching its full moon phase. To determine the specific date when the moon begins to wane, you can consult a lunar calendar or use an online tool that calculates the moon phases based on your location and time zone.
Alternatively, if you are interested in observing the waning moon yourself, you can identify when the moon is full by looking for a completely round and bright moon. Once you've established the full moon, the waning phase begins the following day.
Keep in mind that the waning phase of the moon lasts for approximately 14 days until it reaches the new moon phase. During this time, the moon appears to gradually shrink and become less illuminated each night.
