Why has iCloud stopped syncing calendar changes and reminders on my Mac with my iPhone?

It works fine with my iPad but abruptly stopped working with my iPhone. Changes to my iPhone will not sync with my iMac and vice versa. I have tried various fixes but haven't come up with a solution. My iPhone is a 4s. iMac was new last December. Both have the latest updates.

iPhone 4S, iOS 8, iMac, OS X 10.9.5

Are you syncing contacts and calendars with other accounts in addition to iCloud (Gmail, Yahoo, exchange, etc.)? Check Settings>Mail,Contacts,Calendars>Default Account (in the Contacts section) and >Default Calendar (in the Calendars section) and make sure it's set to your iCloud account.

For what it's worth, I had similar symptoms, but a different- self inflicted- cause. I had acquired over the years two Apple ID's, one associated with a .mac address that we had used as a "family" email, another (based on our company domain/ email) used for personal and business. Since having two Apple ID's has become problematic to say the least, when I upgraded to a new Mac and phone I tried to consolidate and use just one for all iCloud functions, leaving the other .mac address just for email. I was able to do this fine for everything except Calendar. The only "fix" I found was to disable the legacy iCloud account in Calendar preferences, and re-enter everything under the iCloud account I was using as my Main one. iCloud can only see one Apple ID, and I had my calendar data somewhere it could not look.
