During the 1989–1990 school year at Hogwarts School of Witchcraft and Wizardry, Professor Sybill Trelawney taught sixth-year students in Divination class about Ovomancy. Professor Trelawney had her seventh-year students revise Ovomancy in the 1990–1991 school year in preparation for their upcoming Nastily Exhausting Wizarding Tests.
Robert Hilliard, a Ravenclaw Prefect in the 1990s, informed first-years who had just been Sorted into Ravenclaw that this was not considered an unusual pastime within the House. In fact, according to him, not only would other Ravenclaws have no trouble with someone "spend[ing] [their] days and nights" practising ovomancy in a corner of the common room, but one would "probably find a few people to help."
Ovomancy comes from the Latin word 'ovo', meaning 'egg'.
