Hello:
I want to clarify you a thing. Of course, That I know that the year zero
never existed in our calendar.
But the important thing is to celebrate the situation, and don´t waste the
time in boring explanations.
So that nobody become angry the best is to celebrate that two times
31-12-1999 and 31-12-2000.
:-)
