The Yoruba calendar (Kọ́jọ́dá) is a calendar used by the Yoruba people of southwestern and north central Nigeria and southern Benin. The calendar has a year beginning on the last moon of May or first moon of June of the Gregorian calendar. The new year coincides with the Ifá festival.

The traditional Yoruba week has four days. The four days that are dedicated to the Orisa go as follow:

• Day 1 is dedicated to Obatala, Sopona, Iyami Aje, and the Egungun
• Day 2 is dedicated to Orunmila, Esu, and Osun
• Day 3 is dedicated to Ogun and Oshosi
• Day 4 is dedicated to Sango and Oya

To reconcile with the Gregorian calendar, Yoruba people also measure time in seven days a week and four weeks a month. The four-day calendar was dedicated to the Orisas and the seven-day calendar is for doing business.

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).

There are 60 seconds (ọgọ́ta ìṣẹ́jú-àáyá) in 1 minute (ìṣẹ́jú kan); 60 minutes (ọgọ́ta ìṣẹ́jú) in 1 hour (wákàtì kan); 24 hours (wákàtì mẹ́rìnlélógún) in 1 day (ọjọ́ kan); 7 days (ọjọ́ méje) in 1 week (ọ̀sẹ̀ kan); 4 or 5 weeks (ọ̀sẹ̀ mẹ́rìn tàbí márùn-ún) in one month (oṣù kan); 52 weeks (ọ̀sẹ̀ méjìléláàádọ́ta), 12 months (oṣù méjìlá), and 365 days (ọjọ́ mẹ́rìndínláàádọ́rinlélọ́ọ̀ọ́dúnrún) in 1 year (ọdún kan).

The Yoruba traditional calendar is called “KỌ́JỌ́DÁ” 'Kí ọjọ́ dá,' meaning: may the day be clearly foreseen.

The traditional Yoruba calendar (Kọ́jọ́dá) has a 4-day week, 7-week month and 13 months in a year. The 91 weeks in a year added up to 364 days. The Yoruba year spans from 3 June of a Gregorian calendar year to 2 June of the following year. According to the calendar developed by Remi-Niyi Alaran, the Gregorian year 2025 AD is the 10,067th year of Yoruba records of time.^{[1][unreliable source?]} 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.
