One day an armenian boy Henrik Marsepjan went on a trip with his russian friend Vladimir Sepjulnov and his dog Dix. It was a beautiful June day in 2011. What was the exact date?
Last names of out friends consist of months abbreviations, when we switch them for the numbers, we get 391 and 9711. Dog Dix or DIX, that's 509 in Roman numerals. Because they went together, we sum them and get 10611 or 10/6/2011
