Black moon is a reference to one of four astronomical events involving new or dark moons:
|1. The second occurrence of a new moon in a calendar month.||Cannot occur in February. Analogous to the common calendrical definition of a blue moon for months with two full moons.|
|2. The third new moon in a season that has four of them.||Analogous to the Farmers' Almanac definition of a blue moon for seasons with four full moons.|
|3. The absence of a full moon in a calendar month.||Can only occur in February, thus January and March will each have a second full moon (a calendrical blue moon).|
|4. The absence of a new moon in a calendar month.||Can only occur in February, thus January and March will each have a second new moon. As shown in 2014.|

In some aspects of Paganism, particularly amongst Wiccans, the black moon is considered to be a special time when any rituals, spells, or other workings are considered to be more powerful and effective. Not all aspects hold to this belief and only consider it a normal occurrence of the dark moon. Others do not believe any rituals or workings should be conducted at these times.
