Google Calendar integration shows appointments today but they were 2 months ago

Hello community,

i set up my Google Calendar integration like 2 months ago.
And it showed the next appointment in my lovelace.

Since a week it shows appointments that were 2 months ago, but it says its today.

e.g.:

that “Hochzeitstag” - day of when they married was on the 16th of September…
So its shows them wrong.
And only for the main calendar, the holiday calendar is ok.

Does anyone know why and what to do now?

Greetings

The most posible thing I can imagine, it is not the integration, where it goes wrong, but your Google calendar it self.

go to https://calendar.google.com/ and see, if it is there…

Hello there,

that would be the coolest thing, but i checked it just now and the calendar is fine.
I even got the calendar synced on my android phone and my wifes iphone and everywhere but in HA its working.

I now saw it is only for all-day events.
because now the next appointment is saturday, when we will get eggs (Eier) delivered and that is perfectly true:

Do you have another hint maybe?
