Oke Itase or letter of the year (as it is known in Latin America) is the world Ifá divination that is celebrated every first Saturday in June in Ilé Ife, the Yoruba capital of Nigeria.

For several days, Babalawos from all lineages in Nigeria came to Ilé Ife to participate in the ceremonies before divination and to know the messages brought by Orunmila throughout the year. These ceremonies are based on ancient rituals and are still practiced today.
