Halloween

Halloween is one of the celebrated holidays on the Julian calendar. In a common year, it is the 304th day of the calendar. This will be the third sentence ending with the word "calendar". In fiction and real life, Halloween is celebrated by children who go around and play Trick-or-Treat while dressed up as monsters, characters, or objects. Exclusively in fiction, Spooky Shit may go down like farmers' crops coming to life or real monsters showing up and attacking people.
