I’m not a Microsoft Project expert, but I’ve been using project off and on since the mid 90’s and usually know what I want to accomplish with it.  At times, however, I tend to struggle trying to find the commands in the stupid tool ribbon. 

I created a custom calendar to represent a reduced work schedule, but I originally created it with a typo and wanted to remove it.  Try as I might, I couldn’t figure out how to delete or rename the offending calendar using any of the options in the Project Properties ribbon.  Seems like it would make sense to be in there somewhere.  I also tried to find it in the File | Options dialog on the “backstage.” 

I finally found it within the Organizer within View menu (that makes lots of sense).  If you navigate to one of the view selectors you can find the Organizer.  The organizer has all the management options for the objects stored in the global and project templates.  Once you find this, it’s easy to delete or rename your calendar.

Okay, now I feel better.
