Regional One Day

Test cricket is the longest form of the sport of cricket. It is generally considered the ultimate test of playing ability and endurance in the sport.  The name "Test" may have arisen from the idea that the matches are a "test of strength and competency" between the sides involved.

T20 International

One Day International (ODI) is a form of cricket, in which 50 overs are played per side between two national cricket teams. The Cricket World Cup is played in this format. One Day International matches are also called "Limited Overs Internationals (LOI)", because they are limited overs cricket matches between national sides, and if the weather interferes they are not always completed in one day. Important one-day matches, international and domestic, often have two days set aside, the second day being a "reserve" day to allow more chance of the game being completed if a result is not possible on the first day (for instance if play is prevented or interrupted by rain).
