A One Day International (ODI) is a form of 50 overs limited overs cricket, played between two teams with international status, in which each team faces a fixed number of overs, currently 50, with the game lasting up to 7 hours. The Cricket World Cup, generally held every four years, is played in this format. One Day International matches are also called Limited Overs Internationals (LOI), although this generic term may also refer to Twenty20 International matches. They are major matches and considered the highest standard of List A, limited-overs competition.

Limited overs cricket, also known as one-day cricket or white ball cricket, is a version of the sport of cricket in which a match is generally completed in one day. There are a number of formats, including List A cricket, Twenty20 cricket, and 100-ball cricket. The name reflects the rule that in the match each team bowls a set maximum number of overs, usually between 20 and 50, although shorter and longer forms of limited overs cricket have been played.
