Find the Date Puzzle

An International competition is organized on knockout terms in November 2013. The final contestants are from Britain and America respectively. Both of them are handed over the final test paper which they have to fill for evaluation. They have to write their names and date on the paper. When the evaluators are handed over the sheets, they find out that both the guys have same name. In no manner can they identify which sheet belongs to whom.

Can you identify the date on which the competition was held?

Solution:

Competition was held on 11 November. American follows MM/DD/YYYY and British follows DD/MM/YYYY. As the judges were not able to find out which sheet belong to which person because they have same name and dates they written was 11/11/2013.
