Info on upgrading to version 2/3
gotoDate
Moves the calendar to an arbitrary year/month/date.
.fullCalendar( ‘gotoDate’, year [, month, [ date ]] )
IMPORTANT: month is 0-based, meaning January=0, February=1, etc.
This method can also be called with a single argument, a Date object (only works in versions >= 1.3.2).
