The Igbo calendar (Igbo: Ògụ́àfọ̀ Ị̀gbò) is the traditional calendar system of the Igbo people which has 13 months in a year, 7 weeks in a month, and 4 days in a week plus an extra day at the end of the year. The calendar has its roots steeped in ritualism and symbolism; many parts of the Igbo calendar are named or dedicated to certain spirits (Igbo: Mmuo) and deities (Igbo: Alusi) in the Igbo mythology. Some of the spirits and deities were believed to have given the Igbo people knowledge of time. The days, also known as market day, also correspond to the four cardinal points, north, south, east, west.
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. The Nri-Igbo yearly counting festival known as Igu Aro marked March 10, 2012 as the beginning of the 1013th year of the Nri calendar.
In the traditional Igbo calendar a week (Igbo: Izu) has 4 days (Igbo: Ubochi) (Eke, Orie, Afọ, Nkwọ), seven weeks make one month (Igbo: Ọnwa), 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 names of the day's have their roots in the mythology of the Kingdom of Nri. Eri, the sky-descended founder of the Nri kingdom, had gone on to break the mystery of time and on his journey he had saluted and counted the four days by the names of the spirits that governed them, hence the names of the spirits eke, orie, afọ and nkwọ became those of the days of the week. The days also 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 sent down by Chukwu (Great God) in order to establish markets throughout Igboland which they did by selling fish.

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 (maiden [born] on the day of Eke), Mgborie (maiden [born] on the Orie day) and so on were common among the Igbo people. For males Mgbo is replaced by Oko (Igbo: Male child [of]) or Nwa (Igbo: Child [of]). An example of this is Nwankwo Kanu, a popular footballer.
Months and meanings
The following months are in reference to the Nri-Igbo calendar of the Nri kingdom which may differ from other Igbo calendars in terms of naming, rituals, and ceremonies surrounding the months.
The first month starts from the third week of February making it the Igbo new year. 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 (an Nkwọ day on the third week of February), but was postponed to March 10 due to local government elections in Anambra State where the Nri kingdom is located. The Igu Aro festival which was held in March marked the lunar year as the 1013th recorded year of the Nri calendar.
