Calendar dates are shifted after upgrading to Confluence 9.0.1

[sl-admin_upb_de]

Why are the dates in my Confluence calendar shifted by one or multiple days after updating to version 9.0.1? This visual shift is causing confusion and making it difficult to schedule meetings.

To reproduce this issue, please follow these steps:

1. Upgrade Confluence to version 9.0.1.
2. Navigate to the calendar view.
3. Observe that the dates of existing events are shifted one ore multiple days to the right. 

This issue only occurs with all types of calendar (team and private). The time zone is set to UTC+2h. I have tried to use different settings in the calendar widget.
