The fourth millennium AD is a period in history from the 31st to the 40th century. It is a time period that is yet to be experienced, and therefore, difficult to predict what it will be like. However, there are numerous fictional depictions of the fourth millennium AD in various media. The opening is on January 1, 3001 and the closing on December 31, 4000.
