When using any of the standard calendar date variables, what is returned is incorrect. This is true either using epoch dates and formatting with the Date macro, or simply using specific variables.
This appears only to happen for the List View.
For example, I just created an event that began on May 14th and ended on the 15th. When using the variable, startDayOfMonth, it returns 9.
The problem was with the template variables that were used.
The template has been updated to use the right ones. eventStateDateblahblahblah
