Hi Folks,
I have a need to determine the number of business days between two dates-somewhat like the DatePeriodCountCalculator.dayDiff method, but for a holiday & week day calendar I set up. Did I miss seeing something that is part of these packages that would do the job? Or, if that function is not implemented, any tips on how to go about implementing it from a DateCalculator? (I'd be happy to submit whatever I come up with to the project; my initial thought was a new method in DateCalculator, but if it would fit better elsewhere, let me know.)
Thanks!
John
