Sorry but I don't have any clue about the dates however I do know the year as well as the name of the country. The list is as follows-
New Zealand- 1893
Sri Lanka- 1931
Hong Kong is planning about this and it might be done by 2017(just a fact I came across). That's all I can come across. Sorry it went beyond 15 countries because I wanted to give you an option so that you can pick whatever country you would prefer :D. Hope it helped :).
