Julian Date Number/Gregorian Calendar Date Conversions

[Eddie W. Shore]

Dieter,

I meant 1988, not 1998. Typo on my end.

The post was on my blog (see the link in the original post) is for three calculators, not just for the HP Prime. I wanted to get an algorithm down to include code for any calculators that don't have the wonderful DDAYS and DATEADD/DATE+ functions that HP Prime, and most high-end HP calculators have.

Quite frankly, the DDAYS and DATEADD should be on every calculator. In future programs, especially on the HP Prime, I will use these functions.

The DDAYS function is one of my most used and favorite functions!
