The four days that are dedicated to the Orisa go as follow: To reconcile with the Gregorian calendar, Yoruba people also measure time in seven days a week and four weeks a month.
The seven days are: Ọjọ́-Àìkú (Sunday), Ọjọ́-Ajé (Monday), O̩jọ́-Ìṣẹ́gun (Tuesday), Ọjọ́rú (Wednesday), Ọjọ́bo̩ (Thursday), Ọjọ́-E̩tì (Friday) and O̩jọ́-Àbamé̩ta (Saturday).
Time (Ìgbà, àsìkò, àkókò) is measured in ìṣẹ́jú-àáyá (seconds), ìṣẹ́jú (minutes), wákàtì (hours), ọjọ́ (days), ọ̀sẹ̀ (weeks), oṣù (months) and ọdún (years).
The Yoruba traditional calendar is called “KỌ́JỌ́DÁ” 'Kí ọjọ́ dá,' meaning: may the day be clearly foreseen.
With the British colonial and European cultural invasions, came the need to reconcile with the Gregorian calendar: Yoruba people also measure time in seven days a week and 52 weeks a year.
