Weekday labels wrong in month grid view after changing month #354

Closed MikeChuckRoast closed 1 year ago

MikeChuckRoast commented 3 years ago

I installed fullcalendar 5.5.0 plus angular package for Angular 9.1.13. In the month grid view, when I switch to a different month, the weekday labels all shift by 2 days so that the week now starts with Tuesday. However, the grid does not reflect this, so all of the labels are incorrect.

Demo in stackblitz here: https://stackblitz.com/edit/full-calendar-bug?file=src/app/app.component.html

Example screen shot for today: image

Reproduce by clicking the arrow to scroll forward a month, then click back to return. The problem goes away temporarily if I switch to week view and back to month; but then as soon as you scroll the month, the problem returns.

Thanks for the demo but I don't see the same on my side, I click "month", then ">" to go forward a month, then "<" to go back a month and the labels always start with Sunday.

Which browser do you see the issue in? Let me know if I missed something.

I just checked the StackBlitz link, and it appears to be fine for me as well. However, I still see the issue in my actual application (https://rides.downrivercycling.org/calendar). Can you confirm you see the issue on that site? It had reproduced for me in StackBlitz originally as that's where the screen shot came from.

Yes, I also see the issue in your app, although it's hard to tell what the difference is, I wasn't able to reproduce the same in StackBlitz.

I can take another shot at stripping down my application code so it's reproducible. Unless you want to just try it with my full application. It shouldn't be just a build issue, because the problem occurs when I run locally and the deployed version, and the deployed version is built independently from the same code.

A stipped down reproduction would be appreciated, the time saved reproducing will be time spent fixing.

MikeChuckRoast commented 3 years ago

Sorry I left this hanging for so long. I'm a bit stumped, because stackblitz example seems to be the only thing that does work. The problem exists for me locally, and when I deploy to my server. I even did a completely clean build on a different computer, and I still see the problem. Can you please try cloning this locally to see if it reproduces for you: https://github.com/MikeChuckRoast/fullcalendar-bug

Had the same problem. Changing the version @fullcalendar/.. from 5.5.0 to 5.3.1 solved the issue. (Did not try with other version).

If you could try to reproduce this problem in v6, that'd be great. I've added additional debugging templates: https://fullcalendar.io/reduced-test-cases

The problem was resolved for me in 5.6. I'm now on 5.10 and still problem free.

Okay great. Closing
