Ungültiges Datum im Kalender "Anstehende Ereignisse"-Panel auf Safari

[Neil_Evans2 (Neil Evans)]

There appears to be a bug in the Right Sidebar Blocks component on Safari (desktop and mobile), where it displays “invalid date” in the “upcoming events” panel on the right. It works fine in Edge, Chrome and Firefox:

I can’t repro this on safari. Does it work on /upcoming-events route?

[Neil_Evans2 (Neil Evans)]

Thanks for helping me out with this - much appreciated!

Maybe I am doing something wrong, but I tried adding upcoming-events (and also tried /upcoming-events) but it’s not displaying the right-hand panel on that view? It’s showing in the categories I have specified though:

Upcoming events view:

Looks like a problem with moment on Safari?

[Neil_Evans2 (Neil Evans)]

It appears to be related to the specific event, as another event I just created displays fine. Will try to narrow it down..

[Neil_Evans2 (Neil Evans)]

OK - this is really odd.

I created a test event - and it displayed fine. Then I changed the date of this event to match the one that wasn’t displaying - and it also had the same problem - so it appears to be related to the date of the event.

The event in question runs from 3rd Feb 2026 to 5th Feb 2026. If I change it to the previous or following week it displays fine!

Then I tried extending the end date - and got this:

It appears to display fine in the Upcoming Events route?

FWIW there’s another report of this in the plugin topic as well:

Discourse Calendar (and Event)

Hi all! I’ve installed the Right Sidebar Blocks plugin to display upcoming events in the right sidebar using the upcoming-events-list block. However, after creating an event, I keep getting an “Invalid date” error in the upcoming events list. [Capture d’écran 2025-06-17 à 12.14.30] Has anyone encountered this before? Any idea what I might be doing wrong? Thanks a lot in advance for your feedback and support!

[Neil_Evans2 (Neil Evans)]

Any ideas for a workaround?

[JammyDodger]

I don’t know of a workaround, but I can repro using an event date on the single digits of a month (eg 3rd July 2025). This marries up with the wonky ones you and @mpaulhac have given as examples.

From the look of the error in your screenshot above it seems to be dropping a ‘0’ in the single digit date (ie 2026-02-3) for some reason.

[Neil_Evans2 (Neil Evans)]

Thanks for the update - much appreciated! Hopefully a simple fix?

[j.jaffeux (Joffrey Jaffeux)]

I can’t repro even with single digit, but I don’t understand why you don’t just define your date correctly?

Can you share the raw of your post (the markdown) where this event is defined please?

[JammyDodger]

@j.jaffeux

I don’t understand why you don’t just define your date correctly?

I’m just using the Create Event option in the circle-with-a-plus menu. Nothing manual.

[event start="2025-07-03 18:20" status="public" timezone="Europe/London" allowedGroups="trust_level_0"]
[/event]

[j.jaffeux (Joffrey Jaffeux)]

[event start="2025-07-03 18:20" status="public" timezone="Europe/London" allowedGroups="trust_level_0"]
[/event]

There’s no single digit here, so what is the issue?

With this raw:

[JammyDodger]

I don’t know what to tell you?

Something is happening to the date in that calendar graphic on the left that safari doesn’t like.

The error from the post higher up references a date with a 0 missing:

That’s the best I got.

[j.jaffeux (Joffrey Jaffeux)]

I should have enough to fix, even blindly, will look thanks.

[j.jaffeux (Joffrey Jaffeux)]

Ok that should fix it:

FIX: correctly display single digit event in safari

[JammyDodger]

I’ve just updated and it works for me.

[Neil_Evans]

Works for me too! thanks so much for the fast response!
