tyvm, Chip, for the explanation. So this century really began in Jan 1,
2001, not 2000. Interesting.
Certainly glad it was the "C" programmers, not the BAL programmers, that
went wrong.
A good BAL programmer knows that everything is relative "0", not "1".

Re: How can get the Week day ?
Technically, the first year of each century is cc01, not cc00.
Due to an appalling lack of consistency, the C programmers in the
first decade ("0") of the first century ("0") declared the first year
to be "1". :-)
