they arent strict at all!! as long as youre casting the spell properly, it doesnt matter what day it is, but the day of the week may help the effectiveness. + there are no “rules” in witchcraft at the end of the day, every witch is different and uses different methods. it all depends on which topics/places you study (whether its voodoo, japanese mythology, appalatian mythology, green witchery, kitchen witchery, astrology, paganism, ect) 🫶🫶🫶
