Description Gene Nygaard 2005-05-21 14:26:45 UTC
This is a problem involving signs of numbers, with a major mistake in

<nowiki>[[15 March]] [[44 BC]] </nowiki> ([[15 March]] [[44 BC]]) displays as
-0043-03-15 (correct) and 15 March 44 BC (correct)

<nowiki>[[-0044-03-15]] </nowiki> ([[-0044-03-15]]) displays as -0044-03-15
(correct) and 15 March 43 BC (incorrect, should be 15 March 45 BC). 

When BC dates are converted to negative numbers, you need to subtract one from
the [[absolute value]] of the BC date.  Don't convert to 44 BC to a negative
number -44 and then subtract one.  The year 44 BC corresponds to -43, not to
-45.   The year -44 (-0044) corresponds to 45 BC, not 43 BC.  If you get lost,
just go back to the beginning and figure out that zero is 1 BC, -1 is 2 BC, etc.

This has been discussed a long time ago on [[Wikipedia talk:Manual of Style
(dates and numbers)]]
Comment 1 Anders Wegge Jakobsen 2005-05-22 12:50:09 UTC
Fixed in REL1_4 and HEAD.
Comment 2 Gene Nygaard 2005-05-23 14:08:31 UTC
Unless there is a considerable delay time between fixing and implementation, this still 
isn't fixed:  <nowiki>[[-0044-03-15]] </nowiki> ([[-0044-03-15]]) still displays as 15 
March 43 BC which is incorrect, it should be 15 March 45 BC.
Comment 3 Anders Wegge Jakobsen 2005-05-23 14:14:17 UTC
The syncing to the live sites are a manual process, and in this case it
obviously hasn't been done yet. Right now, there are more pressing task with the
upcoming 1.5 release, so please be patient.
