Re: API for week numbers.

[MichaelQuigley@xxxxxxxxxx]

I don't think IBM provides anything for week numbers because there's too 
much discrepancy in what a week number is.  i.e., Does your week begin on 
Sunday or Monday?  And do your weeks begin numbering from the first full 
week the week with the first Sunday/Monday/etc.?

You could code one by multiplying the weeknumber by 7 and adding the 
result to the Lilian date for the 1st of January of the requested year. 
Then you still have to adjust things depending on what week really starts 
the year in your organizations standards.
