One-day is a form of cricket that is completed in a single day, as distinct from Test cricket and domestic first-class cricket, which can often take up to five days to complete or obtain a result. One day cricket, unlike test cricket, always ends with a result in a single day's play. In a one-day match, each team bats only once and their innings are limited to a set number of overs, usually fifty, however, this can vary as a result of poor weather etc.
