It has just occurred to me.

In some parts of Asia the years are still referred to by ways different from the Common Era.  For instance in Japan the year 2010 is Heisei 22 (平成22年).  

In Taiwan it is Minguo 99 (民国99年).

In North Korea it is Juche 99 (주체99년／主体99年).

Next year it will be year 100 in both Taiwan and North Korea.  It is a coincidence though, as the former reckons years from the founding of the Republic of China, while the latter is based on Eternal President, Great Leader Kim Il Sung’s age.
