Bug: Calendar Display and Sync Issues in Planner: Incorrect Day Assignments and Missing Google Calendar Sync

[JBr000]

Description of the issue

In the planner, the calendar is not displaying properly: Monday is empty, and the content of Monday appears in Tuesday (and so on).
The calendar item, when clicked, displays the correct date range (e.g., Monday's time range appears in the Tuesday column).
Additionally, I synced my Google calendar and assigned a time slot for an issue, but this is not showing in Google Calendar.

Your environment

• huly.app online free tier (created yesterday)
• Chrome Version 130.0.6723.58 (Official Build)
• Windows 11 Pro 23H2 - 22631.4317

Steps to reproduce

1. Change issue status to: "To Do"
2. Go to the planner.
3. Select an issue and drag and drop it onto the calendar on the right.
4. Edit dates in the calendar item and select the correct sync calendar.

Expected behaviour

The calendar should display the items on the correct day.
Newly created items should sync with Google Calendar and appear there.

Actual behaviour

• Monday is displayed as empty, and items appear shifted to the following day (e.g., Monday's content is displayed in Tuesday's column).
• Clicking on calendar items shows the correct date range, but items are visually misaligned by one day in the calendar view.
• Events assigned to the Google Calendar in the planner do not appear in the actual Google Calendar, despite selecting the correct sync calendar.
• The bug appears because "today" is Sunday. If I click the arrow in the top-right to move to the next day (Monday), the display then becomes correct.
