My iPad calendar has stopped syncing to my iPhone calendar. I didn't change any settings. I have now switched off the iCloud calendar on my iPhone but don't know how to get it back.

I added items to my iPad calendar yesterday but they wouldn't copy into the calendar on my IPhone. I switched both devices off and on again but to no avail. The calendars were all ticked the same. I have now deleted the iCloud calendar from the iPhone but don't know how to get it back.

My Errands app is also not syncing. If I mark something as Done on the iPad, it's not removing them on the iPhone version.
