A one day international, commonly abbreviated to ODI, is a 50-over-per-side cricket match between two national teams. It is completed in a single day's play.
- The object of a one day international is to score more runs during your allotted overs than the opposition. One team bats first and sets a target, then the other team chases that target. An ODI can therefore end in a win/loss or a tie; it can also be abandoned if playing conditions are unsuitable for completing the match, such as in the case of persistent rain.
- The first one day international was played in 1971 between Australia and England at the Melbourne Cricket Ground. The concept of a shorter form of cricket than Test matches, which last for five days, proved popular and eventually led to the establishment of the Cricket World Cup in 1975.
- In the past, the fixed number of overs allotted to each team in an ODI cricket match could be anywhere between 40 overs and 60 overs. Nowadays, the number of overs has been fixed at 50, although interruptions for rain or other reasons often lead to that figure being reduced in order to fit the match into a single day.
- Each bowler must bowl no more than ten overs in a 50-over innings. If the number of overs in an innings is reduced, the general rule is that each bowler is allowed to bowl a maximum of one-fifth of the total allotment.
- Powerplay overs are the first ten overs of an innings (1st Powerplay) and a five-over block to be chosen by the batting team and completed before the end of the 40th over (2nd Powerplay). During the 1st Powerplay, the fielding team may not have more than two players outside the 30-yard circle; this increases to three players during the 2nd Powerplay. At all other times, the fielding team may not have more than four players outside the circle.
