Data inválida exibida no painel "eventos futuros" do calendário de eventos no Safari

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!
