Look the absolute #1 advice I can give to baby pagans & witches is this.
Your practice is individual, personal, unique. No one, no book, can tell you what your best, most powerful praxis will look like.
In almost all the “starter” witchcraft books I have read, the importance of the full moon as the most potent time of the month has been stressed. The time to do your ritual work, start your spellwork, do your divination, centre your month around this.
For me that’s not the case. My magical month revolves around the dark moon. As a default, that’s when I do important work, when I hold my most elaborate and important ritual. When the veil is thinnest for me and I most easily achieve ecstatic trance. When I honour the one I am oathed to. That’s all a personal thing I discovered over time, that the dark moon is more powerful for me than the full.
No one can tell you what your practice ought to look like but you.
