    Hmm... Interesting use case.. I never really thought much about it.    Doing a GTS (Google That Stuff) ... seems that "solar", "gregorian" and "Christian" are the same. 

    I found this article that defines them a bit differently and provides some conversion formulas..

    I also found this site.. will take a bit to translate javascript into Ninox..

    There is a downloadable javascript file that can be used to reverse engineer the formulas... Seems like I might be walking around the block to go next door on this one.. :)

    Thank you very much for following up the matter for me. I’m logged in to the site you sent and download the file but i dont know what to do.

    i copied this file in a formula but it didn’t work.

    Yeah.. You will have to translate the java script code into Ninox code... That will take a while..
