I have DELETED calendars showing in my iTunes Sync Calendars list!?

Question

iMac late 2009
OSx 10.10.2
iPhone 6 Plus
iOS 8.1.3
Completely Up to Date!
no clouds involved, no calendar subscriptions.
I have had a major problem with my Calendar's calendars, which I have completely repaired using Calendar.  During that process, I had to rename a number of calendars in order to keep track of what I was doing - an intermediate diagnostic step.  Once I'd gotten everything right, exported all the "good" calendars to .ics files, and deleted ALL CALENDARS - both the good ones and the intermediately named ones -  then imported the .ics files back into Calendar... leaving me with ONE FULL SET OF CLEAN CALENDAR data.  When I open Calendars on my mac, I see 33 calendars listed on the left side of the window.
My problem now that I'm ready to put my calendars back onto my phone, is that my Calendars Library (library/calendars) still has many of the intermediate calendar files (that have NOT been DELETED) and in iTunes, the list of Calendars includes all these same intermediate calendars, as well as the new calendars that I want to transfer to my phone.  I would prefer to "select" "ALL CALENDARS" but I can't do that until I can remove the calendars that were supposed to be deleted/removed in the first place.  In other words, I have 33 good, clean Calendars, but there are 71 Calendars in my Calendar Library.
What are the correct steps to remove the Library/Calendars folder so that the iTunes "Sync Calendars" list only shows the 33 good calendars, and not the 38 unwanted (deleted) calendars.
What do I have to do to finish the job?

Answer 1

I have/had the same problem. I tried deleting all the "Library" "Calendar" preference files I could find and like others nothing worked. Like others they would just recreate themselves.
BUT, I did find the solution. Not sure which part worked, but this is what I did.
I quit all the apps, Calendar, and iTunes.
I went into the folder pointed to by job-seeker above:
               <user>
               Library
               Containers
               com.aple.CalendarAgent
               Data
               Library
               Calendars
Manually went through each cached calendar folder and looked in the info.plist for the calendar title listed below "<key>Title</key>" and deleted the parent folders of no longer existent calendars.
Then find an app called "Reminders", open it and you will find all the deleted calendars that you have deleted over the years, they seem to get cached in it, delete them and quit.
Relaunch iTunes and find the deleted calendars in question are gone.
I think you could skip all the above and just try deleting the old calendars from this Reminder app and it may work, but the above is what I did when it worked for me and I do not want to recreate the problem just to verify my theory. ;-)
Hope this helps,
