20 Mind-Blowing Facts About Joseph Stalin
20. Nobody Actually Knows When His Birthday Is
Well, Stalin knows. But we can't exactly ask him. The official Russian records (and Wikipedia) state that he was born on 18 December 1878. However a particular old style Julian Calendar of the time lists his birth-date 12 days earlier on 6 December.
More confusing still is that Stalin actually deliberately changed his own birthday in a ploy to confuse Tsarist Officers, moving the date to the 21st of December and the year to 1881 - the idea being that it would remove him from a number of their official documents and records. In reality all it did was cause all his cards to be late.
