Mattias Engdegård 4ce9c6d0b5 Fix various Calc date conversions (bug#36822) ... * lisp/calc/calc-forms.el (math-absolute-from-gregorian-dt): Rewrite in a way that I understand, and that actually seems to work. (math-absolute-from-julian-dt): Use Julian, not Gregorian, leap year rules for counting days within a year. (math-julian-date-beginning, math-julian-date-beginning-int): Change constants to be consistent with their doc strings and the code: use Rata Die epoch at Dec 31, 1 BC Gregorian proleptic, not Julian. * doc/misc/calc.texi (Date Forms): Correct difference between Julian Day and Rata Die. * test/lisp/calc/calc-tests.el (calc-test-calendar): New test.		2019-08-06 13:59:28 +02:00
