Year 1 BC was a common year starting on Friday or Saturday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a leap year starting on Thursday of the Proleptic Julian calendar. It is also a leap year starting on Saturday, in the Proleptic Gregorian calendar. At the time, it was known as the Year of the Consulship of Lentulus and Piso (or, less frequently, year 753 Ab urbe condita). The denomination 1 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. The following year is 1 AD in the widely used Julian calendar, which does not have a "year zero".
The 2008 Africa Cup of Nations, also known as the MTN Africa Cup of Nations due to the competition's sponsorship by MTN, was the 26th edition of the Africa Cup of Nations, the biennial football tournament for nations affiliated to the Confederation of African Football (CAF). The tournament was staged at four venues around Ghana between 20 January and 10 February 2008. Egypt won the tournament, beating Cameroon 1–0 in the final. With 99 goals, it was the highest-scoring Africa Cup of Nations ever.
Ghana won the right to host the tournament after defeating Libya 9–3 in a vote among Confederation of African Football (CAF) executive committee members in Cairo. South Africa withdrew their bid after winning the right to host the 2010 World Cup.
The entrants were divided into 12 groups. All group winners and the best three runners-up from groups with four teams (groups 2-11) qualified for the finals. Host Ghana qualified automatically. Qualifying took place between 2 September 2006 and 13 October 2007.
