Calc: fix business days calculation (bug43677)
The calculation of business days was broken in 2012 (probably
310e60d9454fe2 or thereabouts) when the date representation changed
epoch so that Jan 1, 1 AD became day number 1 instead of 0. Repair
this, along with an unrelated bug that prevented arbitrary holiday
weekdays from working.
Reported by Aaron Zeng.
* lisp/calc/calc-forms.el (math-to-business-day)
(math-from-business-day): Correct calculation of weekdays using Calc's
current (Rata Die) chronology. Modify loop condition to cope with odd
sets of holiday weekdays.
* test/lisp/calc/calc-tests.el (calc-business-days): New test.
