It is difficult to say that there is no year 0. If we are to look at the Time Line it should appear as
<(2000BC)--------------------(1BC)0(1AD)---------------------(2000AD)> >From a mathamatical perspective, there should be a 0 between BC (Negative numbers) and AD (Positive numbers). If such is the case, then 0 can be taken as 0AD or 0BC (Both mening the same). Thus year 2000 is 2000 Years after 1/1/0000 and is the new millinium. I have not come across any historic record to prove the above right or wrong. But if anyone has any information, please let me know.
