I don't have an answer but it would be helpful to know how you define Julian date. I believe that officially it is a number where 0 represents noon on January 1, 4713 BC. In looking this up it seems it has been redefined in several other ways Explained HERE. How are you defining Julian date?

my mistake when giving you the example. I have corrected it, it should be like below

231 corresponds to 231st day of the year which is August 19th

For that you could use vbscript datediff.

Code: Select all

Year>yyyy
sub>yyyy,1
VBEval>datediff("d","12/31/%yyyy%",(now)),res
MDL>res

Oops. Try this instead.

Code: Select all

Let>vDays=231

Year>yyyy
VBEval>datediff("d","12/31/1899","01/01/%yyyy%"),res
Add>res,%vDays%
VBEval>FormatDateTime(%res%,0),vResDate

MDL>vResDate
