First off a huge thank you for this project, it's most helpful.

I'm seeing two issues with recurring events however:

Issue #1. With monthly recurring events when I "use start date", and call getEvents, I get a list of events on the wrong day, and they start before the event's start date. To reproduce this issue:

a. Create a new event named Event1 with start date of August 1 2014 and end date of August 1 2015. Set recurrence to Monthly, with "Use start date". So this event should, I believe, be scheduled for the first of every month between August 2014 and August 2015.

b. Call getEvents for a specific time period, e.g.

@foreach (CalendarEvent ce in Calendar.getEvents(DateTime.Now.AddDays(-30), DateTime.Now.AddDays(30), "calendar", 1099))
{
  <li>
     @ce.startDate.ToShortDateString() - @ce.content.Name
   </li>
}

Where 1099 is the id of the node that contains my events.

Expected results:

8/1/2014 - Event1

Actual results, and note incorrect day (28th instead of 1st) and the fact that one of these is before my event's start date of August 1 2014:

7/28/2014 - Event1
8/28/2014 - Event1

Issue #2: In both monthly and yearly recurring events, when using either "Use start date" or specifying an iteration, the events returned by getEvents include events that pre-date the event's start date, and actually they go all the way back to year 1. To reproduce this issue:

a. Create a new event named Event2 with start date of August 1 2014 and end date of August 1 2015. Set recurrence to Yearly, with "Use start date". So this event should, I believe, be scheduled twice: Aug 1 2014 and Aug 1 2015.

b. Call getEvents for all events, e.g.

@foreach (CalendarEvent ce in Calendar.getEvents(DateTime.MinValue, DateTime.MaxValue, "calendar", 1099))
{
 <li>
     @ce.startDate.ToShortDateString() - @ce.content.Name
   </li>
}

Where, again, 1099 is the id of the node that contains my events.

Expected results:

8/1/2014 - Event2
8/1/2015 - Event2

Actual results, note events start in year 1:

8/1/0001 - Event2
8/1/0002 - Event2
8/1/0003 - Event2
8/1/0004 - Event2
8/1/0005 - Event2
...
8/1/2012 - Event2
8/1/2013 - Event2
8/1/2014 - Event2
8/1/2015 - Event2

Thank you again for your work on this project!
