Hello Mike,

More accurately -- most Catholic countries -- most of the Protestant countries 
didn't change until much later -- nearly 170 years in the case of Britain and 
her colonies.  A small matter of not being dictated to by the Pope (Papal Bull 
notwithstanding)

Some countries didn't change until early last century (e.g., Romania in 1919, 
Turkey in 1927) and some countries under the dominion of the Eastern Orthodox 
Church use a variant of the Gregorian calendar.  In addition there are the 
various Era-based calendars in use in the Orient.

There are other issues such as what date is New Year but I'll leave that as an 
excerise for the interested reader.

That's the last I'll say on this rapidly-getting-off-topic topic because 
business applications have little need for dates earlier than around 1900.  If 
however you do need historical dates then it would be helpful if they were more 
accurate than the system dates.  The system treats many dates as valid when 
they 
simply didn't exist (e.g., 29th Feb 0004, 10th September 1752 -- in America) 
and, vice-versa, dates that did exist are treated as invalid (e.g., 29th Feb 
1500).

Regards,
Simon Coulter.
