[WP 34S] Julian day number conversion bug

[Damien]

I am sorry not to have been clear enough,

Quote:i would have prefer the full 'astronomic' implementation

what i wanted to say is that astronomers need to count years logically, taking the year before 1 AD as 0, and the year before that as -1, it becomes easier to make calculations.
If you want to compare past events from different calendars, the easiest way is to convert the date of each event into julian day number, then go back and forth to year count for easier comparaison.
like 880 BC. = JD 1400000 (more or less).
For this purpose, i think it would be interesting to have JDN conversion working for negative date.

Cheers,

Damien.
