Unless Congress takes action, effective December 1, 2009, the rules regarding how time periods are calculated in Federal courts are changing as are some of the time periods. Under the current version of Rule 6 of the Federal Rules of Civil Procedure, intermediate Saturdays, Sundays, and legal holidays are excluded when calculating periods less than 11 days, but not when calculating periods 11 days or longer. The version of Rule 6 effective December 1, 2009, does not exclude intermediate Saturdays, Sundays, or legal holidays.
