This works equally well for concealing other atypical aspects you might have - not just the fact that you practice witchcraft. Almanacs will tell you when the Moon is between Zodiac signs, as well - they will refer to it as being “Void of Course.” Normally, one wouldn’t work Lunar magic during this period, but it is traditional for witches to work magic that either requires extreme secrecy or is concerned with extreme secrecy during this period. There’s even stories about criminals committing crimes during these periods in order to conceal them metaphysically. Needless to say, please don’t commit any crimes after performing this spell.
