Weekly view doesn't show first week of new year 2025

Same problem here.

Core: 10.3.10
calendar_view: 2.1.x-dev updated 18 Aug 2024 at 19:46 UTC

• calendar_view_w52-2024.png → : This week is correct, there are no events and all the dates are correct.
• calendar_view_w01-2025.png → : This week is wrong, events should be visble in this week and the dates (month, year, days) are wrong.
• calendar_view_w02-2025.png → : This week is correct again, events are visble and the dates (month, year, days) are also correct.

We are having this same problem.

I see the same. I have a week view in my case and it just has:
Week 01 - December 2024
The dates that are mentioned are: 1/01/2024 to 7/01/2024.
ISO Week 01 2025: December 30, 2024-January 5, 2025.
So it probably takes the first week of the year, which in this case is the first week of 2024 as the Monday is in 2024.

Any news on that?

Hello,
I see that there's a problem with navigation to the first week of 2025, because I get the following case:
Week 01 - 2024 (1,2,3,4,5,6) which is the first week of 2024.
After analysis, the problem comes from a borderline case of code:

public function buildCalendars(int $selected_timestamp): array {
 $year = date('Y', $selected_timestamp);
 $week = date('W', $selected_timestamp);
// dd($selected_timestamp, $year, $week);
 $calendars[$year . W' . $week] = $this->buildTable($year, $week);
 return $calendars;
 }

Indeed, when we enter the selected_timestamp 1735599600 (31/12/2024 00:00:00)
we see the following values: Year = 2024 & Week = 01, i.e. the first week of 2024.
After some research, it seems that this error is caused by a borderline case of format(‘W’) (found here: https://bugs.php.net/bug.php?id=65730).
To avoid this problem, change the :
$year = date('Y', $selected_timestamp);
with option 'o'
or the doc says:

ISO 8601 week-numbering year. This has the same value as Y, except that if the ISO week number (W) belongs to the previous or next year, that year is used instead.

There is still a problem with the view title. It says: 'Week 01 - december 2024'
Because the default title is:
[date:custom:\W\e\e\k W - F y]
If you want the right year, you can change it to 'o' like:
[date:custom:\W\e\e\k W - F o]
In the configurations and code. However, the month is wrong, so we get :
Week 01 - december 2025
It remains to be seen how this particular case can be managed.
