From the Grammar Nazi:  There was no year "6 AD".  There is " __ BC" or "AD __", because it's grammatically incorrect to say "the year 6 the year of our Lord".  And there was no "AD 6" either, because at the time no one used a calendar based on an estimate of the year of Jesus' birth.  That year would have been known as "758 AUC" or 759 depending on who you ask

From my brother the math teacher:

Actually it has already happened 2000 years ago in the year 6 AD.
It is now 2006 so it does not quite work out.

01:02:03 04/05/06  should be  01:02:03 04/05/2006.

This is the state of our mathematics.
