Calendar app displays event start times an hour late on main view

Calendar changing the start time on the main view.


Recently, some (not all) of my calendar events are displayed with the start time an hour late. The events in the pop up are correct, e.g. in 2 example screenshots the starts are 14:15 and 13:00, but the time shown on the grid (in pink and green) are an hour later.


It's not a time zone issue, and it doesn't seem to have anything to do with an 'alert 1 hour ahead.'


I'm bemused. 🫤

Hi there ,

By default , your calendars & events use the time zone set in Settings on iCloud.com .

Go to icloud.com > calendar > tap … three red dots (top left) > settings > formats &

time zone > ✅ enable time zone support > X to exit .


When time zone support is on when you create an event , you will be able to choose any zone from a pop-up menu . Your calendar events will change to the new time zone .

The changes appear on every device with Calendars turned on in iCloud settings .

Time zone support needs to be turned on for each individual device ( repeat the directions above for each device) .


This link is for the Apple Support page with the instructions https://support.apple.com/guide/icloud/change-the-time-zone-


This pic is the setting in General > Settings > Data & Time







This pic is the Calendar format on icloud.com


If you're not sure about these directions , don't hesitate to create another post for more clarity , I'll see it and we'll make sure we get this .
