iCloud Calender changing dates and times of events after input
My iCloud calender is changing the dates and times of events I enter. The calender enters every event from November to March, 3 days earlier then my entry and changes the time to 11pm on all entries. When I key in an event on my iphone it accepts it on my iphone. When it appears on my iPad calender it is 3 days earlier at 11 pm. The reverse also happens, when I input an event on my iPad It records correctly on the iPad, but shows up on my iphone calender 3 days earlier at 11pm. I logged into my iCloud calender on my lap top to see what was happening. I entered a new event directly onto the iCloud calender in iCloud.com . The event moved instantly to 3 days earlier at 11pm. This leads me to believe the problem is with iCloud and not the iphone, iPad, or laptop. It only does this for the months November to march. Raising the question is it something to do with daylight saving time changes? We live in Ireland. I have checked the settings on my iCloud account and they are in the right time zone.
My iCloud calender went back to previous years and changed the entries in the months of November to March all to 11pm. My husband is having the exact same problem on his devices. He has a separate Apple ID. We tried all our devices in another house yesterday connected to another WiFi in case our WiFi was causing the problem. The problem still existed. So this cuts out the WiFi as a cause. We have contacted Apple customer care. No answers as yet. Can anyone help? This is driving us crazy. Thank you.
