Find today's traditional market day in the Igbo 4-day cycle (Eke, Orie, Afor, Nkwo). Check any date past or future. Essential for traders, cultural events, and traditional ceremonies.
The Igbo market day system is one of Africa's oldest continuous calendar traditions, predating colonial influence by centuries. It operates on a simple but elegant 4-day cycle: Eke, Orie (Oye), Afor, and Nkwo. This cycle runs continuously without interruption, independent of the Gregorian calendar's weeks and months.
Seven 4-day market weeks make up one Igbo month (28 days), and 13 months make one Igbo year (364 days). The system is still actively used across southeastern Nigeria for commerce, social planning, and cultural events. Many towns hold their main market on a specific day of the 4-day cycle — Onitsha's famous market peaks on Nkwo days, while Aba is busiest on Eke days.
Since the 4-day cycle is continuous, any date can be mapped to its market day using modular arithmetic from a known reference point. January 1, 1970 (the Unix epoch) was an Eke day. By counting the number of days from this reference to any target date and taking the remainder when divided by 4, we can determine the market day for any date — past or future.
Use the calculator above to see today's market day. The 4-day cycle (Eke, Orie, Afor, Nkwo) runs continuously regardless of the Gregorian calendar.
The traditional Igbo calendar uses a 4-day week (Eke, Orie, Afor, Nkwo) that cycles continuously. Each day has cultural significance and is associated with specific markets, deities, and naming conventions.
The 4-day cycle is universal across Igboland, but each town has its own "big market day" when trade peaks. For example, Onitsha's main market day is Nkwo, while Nnewi's is Afor.
Yes! The Yoruba have a 5-day cycle, the Akan (Ghana) have a 6-day cycle (Adae), and many other West African cultures have their own traditional calendar systems based on market cycles.
