Witchcraft is the use of magic by a person called a witch. Traditionally, "witchcraft" means the use of magic to inflict supernatural harm or misfortune on others, and this remains the most common and widespread meaning. According to Encyclopedia Britannica, "Witchcraft thus defined exists more in the imagination", but it "has constituted for many cultures a viable explanation of evil in the world". The belief in witches has been found throughout history in a great number of societies worldwide. Most of these societies have used protective magic or counter-magic against witchcraft, and have shunned, banished, imprisoned, physically punished or killed alleged witches. Anthropologists use the term "witchcraft" for similar beliefs about harmful occult practices in different cultures, and these societies often use the term when speaking in English.

September 22 is the 265th day of the year in the Gregorian calendar; 100 days remain until the end of the year.
