Calendar week view displays events spanning overnight incorrectly

[TypicalDan]

Describe the bug
Week view on the calendar displays events spanning overnight incorrectly, placing the start and end blocks on the same date, not spanning from day 1 to day 2

For example, if the start is 23:00 2026/1/1 and the end is 03:00 2026/1/2, week view shows 23:00 til 23:59 on 2026/1/2 as well as 00:00 til 03:00 on 2026/1/2

To Reproduce
Steps to reproduce the behavior:

1. Create an event spanning for example 23:00 2026/1/1 til 03:00 2026/1/2
2. Observe the calendar in week view

Expected behavior
Week view calendar shows from 23:00 til midnight on 2026/1/1 and from midnight til 03:00 2026/1/2

Screenshots

Additional context
Many events accidentally clip over midnight due to timezones, this would make those events difficult to follow

I'm not able to reproduce this, could you provide the source of an event which has this issue

I'll try recreating the issue again myself, just to make sure it's not user error 😅

I've just attempted to reproduce the error and it's uuh fixed? I can't seem to reproduce the error now, so may be best to close this.

Nevermind, I've figured out how to replicate the issue.

1. Create an event that spans overnight on Friday to Saturday
2. Set the repeat: parameter to weekly, then select Friday and Saturday

The resulting graph shows 3 blocks on the week of creation:

• 23:00 til 23:59 on Friday
• 00:00 til 03:00 on Saturday
• 23:00 til 23:59 on Saturday

Each week after:

• 23:00 til 23:59 on Friday
• 23:00 til 23:59 on Saturday
  No block for 00:00 til 03:00 on Saturday

Different issue, should I make a new issue?
