The Ewe are the major ethnic group in southern Togo, as well in eastern Ghana, and they have a really neat way to name children. Babies are given a temporary name based on the day of the week they were born, and are then given a proper name a week later (some sources say it’s when there’s have a better sense of the baby’s personality). The birth day name will usually still stay as one of their names, and the name can actually change if later siblings are then born on the same day of the week. There are similar naming conventions with other groups in Ghana and other parts of West Africa
