The Yoruba week consists of four days. Traditionally, the Yoruba count their week starting from the Ojó Ògún, this day is dedicated to Ògún. The second day is Ojó Jákúta, the day is dedicated to Sàngó. The third day is known as the Ojó Òsè – this day is dedicated to Òrìshà ńlá (Obàtálá), while the fourth day is the Ojó Awo, in honour of Òrúnmìlà.

The Yoruba calendar (Kojoda) year starts from 3 to 2 June of the following year. According to this calendar, the Gregorian year 2021 is the 10,063th year of Yoruba culture, which starts with the creation of Ìfẹ̀ in 8042 B.C.
