iCloud/Google calendar sync issues on OS X 10.9.1
You can't create events without a calendar to put them in, and you can't create calendars without an account. Since you have no available cloud service, you need to create the calendars in the On My Mac account.


Completely log out and remove all accounts that could store calendars, including iCloud and Google.
Open Calendars → Preferences → Accounts (Not Calendars → Accounts).
Select the On My Mac account and check the Enable this account box.
