Ethiopia
Ethiopia is the cradle of the human, there we found Australopithecus's bones on its area. Ethiopia has very rich culture, it has its own caledndar with 12 months of 30 days and 13th month of 5 or 6 days. Ethiopian year starts 11th September and it is 7 years and 8 months delayed to gregorian calendar. They have their own writing system (which I like very much) and another interesting thing is that they don't have surnames, they use their father's and sometimes also grandfather's name.
