The Igbocalendar is the traditional calendar system of the Igbo people from present-day Nigeria. The calendar has 13 months in a year, 7 weeks in a month, and 4 days of Igbo market days in a week plus an extra day at the end of the year, in the last month. The name of these months was reported by Onwuejeogwu. Although worship and spirit honoring was a very big part in the creation and development of the Igbo calendar system, commerce also played a major role in creating the Igbo calendar. This was emphasized in Igbo mythology itself. An example of this is the Igbo market days of which each community has a day assigned to open its markets, this way the Igbo calendar is still in use. Some Igbo communities have tried to adjust the thirteen month calendar to twelve months, in line with the Gregorian calendar. The calendar is neither universal nor synchronized, so various groups will be at different stages of the week, or even year. Nonetheless the four-eight day cycle serves to synchronize the inter-village market days, and substantial parts do share the same year-start.
Market days
Igbos generally have four market days, namely: eke, orie, afor and nkwo. The market days according to the Igbo calendar follow each other sequentially as shown below:
Eke
Orie
Afor
Nkwo
In various parts of Igboland, each community has a market named after the aforementioned four market days, e.g., Eke market, Afor market.
System
In the traditional Igbo calendar a week has 4 days , seven weeks make one month, a month has 28 days and there are 13 months a year. In the last month, an extra day is added. The traditional time keepers in Igboland are the priests or Dibia.

The days correspond to the four cardinal points, Afọ corresponds to north, Nkwọ to south, Eke to east, and Orie to west. These spirits, who were fishmongers, were created by Chineke in order to establish social system throughout Igboland. While there are four days, they come in alternate cycles of "major" and "minor", giving a longer eight day cycle. An example of a month: Ọnwa Mbụ

Use
The Igbo calendar is not universal, and is described as "not something written down and followed... rather it is observed in the mind ofthe people."
Naming after dates
Newborn babies are sometimes named after the day they were born on, though this is no longer commonly used. Names such as Mgbeke, Mgborie and so on were common among the Igbo people. For males Mgbo is replaced by Oko or Nwa. An example of this is Nwankwo Kanu, a popular footballer.

The Nri-Igbo calendar year corresponding to the Gregorian year of 2012 was initially slated to begin with the annual year-counting festival known as Igu Aro on February 18.
