IPad 2 not syncing Calendar to other devices through iCloud

Question

My iPad 2 is not syncing Calendar events to other devices through iCloud
Devices:  MacBook Pro (Mountain Lion 10.8.2), iPhone 3GS (iOS 6.0), iPad 2 (iOS 6.0)
iPad 2 Settings: 
   iCloud settings: Calendars 'ON'
   Mail, Contacts, Calendars: Default Calendar:  Calendar; Sync:  All events
   Shared Calendar Events:  'ON'
   Within Calendar App:  Calendars checked:  Home, Calendar
iPhone 3GS Settings:
   Identical to iPad 2 settings
MacBook Pro iCloud Calendar: Home and Calendar checked
I set up the following test event entries for the same date to see what was coming up in each device above:
  1-From iPad:  iPad to iCloud test
   2-From iPhone:  iPhone to iCloud test
   3-From iCloud.com:  iCloud.com to iCloud test
   4-From MacBook Pro:  Launchpad Calendar App to iCloud test
(The last two entries may be redundant, but I wanted to cover all possibilities.)
I then I checked the Calendar App for each of the above devices for "events" 1, 2, 3, and 4 above.
The iPhone Calendar App had "events" 2, 3, and 4
The MacBook Calendar App through LaunchPad had "events" 2, 3, and 4
iCloud.com had "events" 2, 3, and 4
The iPad, however, had "events" 1, 2, 3, and 4
Only the iPad had all events entered from all devices.  This creates a problem, of course, since I almost always have the iPad with me, and that's where I make additions/changes to Calendar, Contacts, Notes, and Reminders. Dependability across the Cloud is pretty important!  What can I do to resolve this?
N.B., Contacts and Reminders synced successfully across all devices through iCloud.  Notes, on the other hand, showed a different problem.  When I created a "Test from devices" note, the iPad and the iPhone showed the additions to the note from each device, including the MacBook.  The MacBook only showed what had been written from the MacBook.  Hmmmm...
Any help here would be greatly appreciated!

Answer 1

First check that all your settings are correct, that calendar syncing is checked on all devices (system preferences > iCloud on a mac and settings > iCloud on a iPhone, iPad or iPod).
Make sure the calendars you are using are in your 'iCloud' account and not an 'On My Mac', 'On My Phone' or other non iCloud account (you can do this by clicking/tapping the calendar button in the top left corner of the application ), non iCloud calendars will not sync.
If you are sure that everything is set up correctly and your calendars are in the iCloud account, you might try unchecking calendar syncing in the iCloud settings, restarting your device and then re-enabling calendar syncing settings.
