Yes - I used Lilian date and a multiple of 7 combined with the Scandinavian definiton of week numbers. I got it right in the end..

Emne: Re: [COBOL400-L] API for week numbers.

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.

[COBOL400-L] API for week numbers.


I need an API that can receive weeknumber/year and return a date/date
range.(Please enclose parameter description as well) I'm already using
CEEDATE, CEEDAYS and CEEDYWK, but I can't see that function in any of

Any ideas?
