2019 English cricket season
The 2019 English cricket season will run between 26 March and 26 September. It will be the 120th in which the County Championship has been an official competition and will feature first-class, one-day and Twenty20 cricket competitions throughout England and Wales.
Twenty20
Twenty20 cricket, sometimes written Twenty-20, and often abbreviated to T20, is a short form of cricket. At the professional level, it was originally introduced by the England and Wales Cricket Board (ECB) in 2003 for the inter-county competition in England and Wales. In a Twenty20 game the two teams have a single innings each, which is restricted to a maximum of 20 overs. Together with first-class and List A cricket, Twenty20 is one of the three current forms of cricket recognised by the International Cricket Council (ICC) as being at the highest international or domestic level. 
A typical Twenty20 game is completed in about three hours, with each innings lasting around 90 minutes and an official 10 minute break between the innings. This is much shorter than previously-existing forms of the game, and is closer to the timespan of other popular team sports. It was introduced to create a fast-paced form of the game which would be attractive to spectators at the ground and viewers on television.
