Letter: Ian Griffiths criticism

ERIC Huchinson's criticism of Ian Griffiths (Letters, 10 May) founders on just one point, his confusion between age and date. Age is counted from zero, whereas the Christian calendar starts from 1 January AD1 - the previous day being regarded as 31 December 1BC. It is this lost (non- existent) "Zero AD" that pushes the start of the third Christian Millennium back to 1 January 2001. Unfortunately, Ian Griffiths is also somewhat previous in his assumption that the computer industry will have no problems from 1 January 2001 - not because "01" is greater than "00" but because it is still less than "99".
