Sorry you are correct there is a bug with this method.

    public static Integer skipToNextBusinessDay(DateTime pDate){
	   Datetime tmpDateTime = Datetime.newInstance(1985,6,24);
	   Integer returnInt = 0;
	   Long dayOfTheWeek = Math.mod(pDate.getTime() - tmpDateTime.getTime(),7);
	   
	   if(dayOfTheWeek == 0){
	      returnInt = 1;
	   }
	   if(dayOfTheWeek == 6){
	      returnInt = 2;
	   }

       return returnInt;
    }

 It was late at night when I sent it. This new method should work just fine.

Thanks Mike,

I'm running into one small glitch.  When the events get created, I'm missing how to add the missed days for the weekends.  For example, if January has 80 hours, that would mean 10 event records should be created.  What is happening is that 8 event records are created because it passes over Saturday and Sunday, but those days are still counted in the recurrence.  I'm probably just missing something simple in my code.

Here is the trigger method with all associated helper methods:

private static void doCreateResourceEvents(List<ProductManagement__c> inNew, Map<Id, ProductManagement__c> inOld)
    {  	

		RecordType rt = [Select Id From RecordType Where Name = 'Service Delivery Event' and sObjectType = 'Event'];
    	
    	List<Scheduling__c> schedulingNew = [Select Hours__c, Month_Index__c, Resource__r.Id, Resource__r.User_Id__c, ProductManagement__r.Id From Scheduling__c Where ProductManagement__c in: inNew];
		
		List<ProductManagement__c> PM = new List<ProductManagement__c>([Select Pricing__r.Opportunity__c From ProductManagement__c Where Id in: inNew]);
		Set<Id> opIds = new Set<Id>();
		for (ProductManagement__c cs: PM) {
			opIds.add(cs.Pricing__r.Opportunity__c);
		}
		
		List<Project_Request__c> PR = new List<Project_Request__c>([Select Id From Project_Request__c Where Opportunity__c in: opIds]);
		
		List<Event> evs = new List<Event>();
	
		for (Scheduling__c s : schedulingNew) {
			
			if (s.Hours__c != null && s.Resource__r.User_Id__c != null 
				&& s.Resource__r.Id != inOld.get(s.ProductManagement__r.Id).Res1__c 
				&& s.Resource__r.Id != inOld.get(s.ProductManagement__r.Id).Res2__c 
				&& s.Resource__r.Id != inOld.get(s.ProductManagement__r.Id).Res3__c 
				&& s.Resource__r.Id != inOld.get(s.ProductManagement__r.Id).Res4__c

				Integer recurrenceInterval = math.round((s.Hours__c / 8)-1);

				Integer hours = math.round(s.Hours__c);

				Integer remainder = math.mod(hours,8);

				if (remainder > 0) {
					recurrenceInterval = recurrenceInterval + 1;
				}

					firstDayOfMonth = firstDayOfMonth.toStartOfMonth();
				}

					firstWorkDayOfMonth = firstWorkDayOfMonth.addDays(1);
				}
				else if (intStart == 2) {
					firstWorkDayOfMonth = firstWorkDayOfMonth.addDays(2);
				}
				

				Date endDate = doConvertDateTimeToDate(firstWorkDayOfMonth);
				endDate = endDate.addDays(recurrenceInterval);
				
				Integer intEnd = skipToNextBusinessDay(endDate);

				if (intEnd == 1) {
					endDate = endDate.addDays(1);
				}
				else if (intEnd == 2) {
					endDate = endDate.addDays(2);
				}

				Event e = new Event();
				e.IsRecurrence = true;
				e.RecurrenceDayOfWeekMask = 62;
				e.RecurrenceType = 'RecursEveryWeekday';
				e.OwnerId = s.Resource__r.User_Id__c;
				e.RecordTypeId = rt.Id;

				e.RecurrenceStartDateTime = firstWorkDayOfMonth;

Do you see what I'm missing?

I am not sure what you are missing but the method that I provided to you is set up to add a 0, or a 1 or a 2 to the interval.

So if the end date is on a Saturday then my method will return a 2. You would add that 2 to the addDays() calculation.

Mike,

Do you have an example of setting the event field values by chance using your skipToNextBusinessDay method?  I'm using your method and it is creating the correct number of events, but it is creating them over the weekend.  My knee jerk reaction is that I'm improperly setting the field values somehow.
