"AD 0" is a perfectly meaningful label. It refers to the year before AD 1; that year is also known as 1 BC. Likewise, AD -1 is 2 BC, and so on. This kind of year numbering is common in astronomy, and was written into the latest version of ISO 8601. The use of AD year numbers below 1 is, of course, contrary to convention in less technical contexts. -zefram _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
