I know how Ada is spelled.  But ADA.people is my word, and I spell it
how I please.  (ADA is an acronym standing for "Ada Discussion and
Admiration"...)

If that C.hackers bit is aimed at me, I offer you this quotation for
your .signature:
	The longer I program in C the better I like Ada.  (me)

I would point out that Webster's dictionary does not contain ALL knowledge...
It's not a matter of where *I* start counting.  It's a matter of how our
calendar works.  The Japanese recently started a new calendar:  the first
year in that is Year 1 of whoever.  Lots of calendars work the same way.
The first decade of the present system would have been 1 to 10.

The complexities in human calendar systems are precisely the reason why
computer systems count days or seconds or whatever from an arbitrary
epoch.
