I have a client who has custom fiscal years enabled (I didn't do this, don't yell at me). It's already set up going several years into the future, with a July 1 start date for each year. Recently they decided to switch their start date to Aug 1 starting this coming year. So FY 2012-13 is going to end up being 13 months long (July 1 2012 - July 31 2013).
Is there any way to model this in SF? They'd prefer not to retroactively change past years to start Aug 1.
When I attempt to change the start date of any of their custom fiscal years, I get an error "One or more adjacent years is a Gregorian year and therefore may not be automatically adjusted. Please fix blocking errors and retry."
