Adedayo is of Nigerian origin, specifically from the Yoruba ethnic group. The name translates to "Crown arrives/crowns have come" and is often used as a reference to the birth of twins. It signifies the arrival of twins because twins were considered a blessing in ancient African societies, signifying abundance and prosperity. This name was traditionally given when twins were born, but it can also be used for any childbirth.
The name Adedayo experienced fluctuations in popularity over the years, with a noticeable spike in 2015 and a steady decline thereafter. However, it remains relatively uncommon overall, with only 72 recorded births between 1974 and 2023.
