A contest is held on international level in December 2013. The finale of it is between an American and a British kid. Only name and date have to be mentioned on the paper for checking purpose. But when the checkers check it, they find out that both of them have same names. The papers cannot be told apart in any manner now.
What is the date of competition ?
The date is 12 December 2013. For any other date, the checkers would have been able to identify the papers. Why? Because the British people write dates in Day/Month/Year Format and the American people write date in Month/Day/Year format. On 12 December, the date and month will be the same and thus there is no way to distinguish when the names are same as well.
