This is a beta version of a spreadsheet based online app that calculates Duckworth-Lewis (D/L) par scores and targets for rain-interrupted limited-overs cricket matches. It uses the 'Standard Edition' method for calculation that is based on publicly published tables and formulas by the ICC.  International matches use the 'Professional Edition'. the details of which have not been publicly published by ICC and uses the 'Stern' method for calculation. Per ICC laws, the Standard Edition should be used for all matches where the Professional edition is not available. Please report any bugs to

Enter the total number of overs that the match was to be played for at the start of the match. The max allowed value is 50.
