And flashed. ;-)
I just updated to v3.3 3734 (calc_ir_full.bin) and did some tests.
Here are the results, as usual in d.my mode:

Code:

-18.032002   DATE->    x:18  y:3  z:-2002    // year now is correctly negative

-18.032002   D->J      989904                // returns correct JDN now

 989904      J->D     -18.032002             // returns correct date
                       Monday                // but still wrong weekday !

-18.032002                                   // another attempt, using DAYS+,
 ENTER  0    DAYS+    -18.032002             // still shows the same error
                       Monday                // in the weekday display

-18.032002   WDAY      7                     // Sunday is correct
                       Sunday                // obviously the 34s knows better ;-)

So there still is a bug in the weekday displayed along with the results returned by J–>D and DAYS+. Possibly other date functions are affected as well. On the other hand, the dedicated WDAY function returns the correct result.

BTW J–>D still accepts negative input. I think this should get corrected as well.
