My calendar on both my iPhone 5 and iPad Air is beyond screwed up. The most common problem is that an entry moves from the time I set for it.
I live in France but I purchased the phone in New York. I thought I found the problem to be related to a time zone preference.
It always defaults to New York no matter how many times I change it to Central European Time.
So I started specifying the Paris time zone on every entry. Sometimes it works, sometimes it doesn't.
And when I travel to another time zone I have no idea if any of my entries are accurate, mostly not. I really have a very simple calendar life. No linking with other people or work accounts. I don't want to completely reset my devices.
Any thoughts on how to resolve this?

Check the following "Settings". Make sure under "General > Date & Time", that your iPhone is showing the correct "Time Zone" You can either have the iPhone determine this automatically (by turning on the "Set Automatically" switch) or you can set it for a specific location. Do note that in order for this to set itself automatically you need to have location services enables as well.
The next thing I would check is "Settings > Mail, Contacts, Calendar" and make sure in the "Calendar" section that you've enabled "Time Zone Support".
