Anti-Christ,
Articles in french were released about 3 months after the English edition. If I can remember well, it was this way until sometimes in the 1980s. Now, regarding when it started, and if everything was translated, I don't know.
However, this explains the differences in the dates.
By the way, even if you probably chose your nick name to show your oposition to the WT, it is still a name in oposition to Jesus himself.
I wouldn't want to be you.
