icloud not syncing properly across my devices

The syncing on my devices is terrible. I update my iphone calender and sometimes it syncs with my ipad and imac and sometimes it doesn't. I just reset the calender on my iphone and now I want to sync the events on my imac calendar to the device but it just doesn't want to sync.

I plugged my phone into itunes and it says that the events are being syncing through icloud and it doesn't give me any other option.

Please let me know asap thank you.

hello?

Hi, sometimes some threads get missed, and sorry you didn't get a answer earlier.

Whenever I have had issues with iCloud, I have always signed out of iCloud on both devices, and restarted them, and then signed back into iCloud on both devices.
I would say thrash a .plist, but you can't do that on your iPhone. . . . thats all I have.
