This is a pool for predicting the date at which the number of articles (as defined by the official article count presented on the Special:statistics) in the English Wikipedia reaches 20,000,000 (twenty million). The person who comes closest to the actual date is the winner (of eternal fame). The current number of articles in the English Wikipedia is 6,913,056.

This pool will be closed for entries when the English Wikipedia article count reaches 16,000,000 (80%), so be sure to place your guess before then. This pool opened on September 9, 2007, shortly before the 2,000,000th article was created.
