Is it possible to change the length of a single iteration?
Yes, you can override how many weeks long a specific iteration will be, to deal with cancelled sprints, holidays, etc. Click on the start date in the iteration header, and enter the desired # of weeks in the popup window that appears. Iterations that have been adjusted will display with the start and end date in a different color (yellow). To revert the change, click on the iteration’s date again and click the revert button.
