Read "The Story of the Youth Who Went Forth to Learn What Fear Was" from #grimmsfairytales to my eldest. The title is a good recap: The MC has to sleep in a haunted house, spooky stuff happens each night, etc. We noticed that in the wording of the story as told, on the second night the spooky stuff all happens after midnight and before the clock struck twelve.
Question for the #folktales slash #medieval hive mind: Is this a storytelling technique, or did midnight not used be be twelve?
