1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
Now ask the kids what is more difficult to learn, English or Arithmetic?
(when the decade changes on the same row).
The decade does not change on the same row.
Each row is a single decade.
Isn't the point that the "twenties" start on the row above the rest;
each row spans 2 decades (the "nineties" started when 1989 became
1990, not 91)
The ultimate example of zero/one based confusion is in Java when
creating a date - days are 1 based, but months are zero based, so
new GregorianCalendar(2008, 5, 20)
returns the 20th of April. (to avoid confusion you need to use the
enum Calendar.MAY)
I think it was genuine mistake rather than intentional, but you can
imagine the bugs that has caused. I doubt many bugs have come from
XPath's 1 based index.
