I am a Japanese.

  "January 7, 1989" is the date that our current emperor was 
enthroned. Each emperor had his own eras. Some emperors changed their 
eras when a disaster or evil thing had happened.
As our imperial family has continued for more than 2000 years, there 
are hundreds of eras in Japanese calendar.

I don't think it is realistic for NSCalendar to have Japanese era 
database.
As our emperor's birthday is a national holiday, I know the date.
But I don't remember the date when Heisei era began. :-)

I am rather interested in Maya calendar that defines the date of the 
end of the world. :-)
