I calendar time zone
Duplicate iPhone calendar times solved. Go into your calendar event and click edit. click on the start time and you’ll have the ability to change the time zone for that event. When I did this for one event, it fixed all of them because for some reason the iPhone calendar does not only have time zone capability for the phone, but for the specific event. I do not know why my phone changed my time zones in the calendar but at least this fixed it. Good luck
