+1 - I'd call this the best "standard" set of calcs for this purpose, especially in a CL program. In RPG, I'd use the built-in date arithmetic, or use embedded SQL.

The CEE* APIs are your best friend for lots of things!

Hello all,


Is there a standard set of calcs out there to handle subtracting days from a Julian date where it goes across years? We have a report that blew up today because it tried to subtract 7 days from today's date and got a value of "2019999". I guess I thought Julian date calcs on the system knew how to handle that scenario. Thoughts?
