Hi,
I forgot about the format. It's as follows:
<div class="event-date">${eventDate(%d. %b %G)}</div><div class="event-title">${title}</div>
Does the event occur through 2021?
There were two events in the list showing the strange behaviour. Both were on a single day. I also added test events from 1st to 4th, that way I found that from the 4th on it showed 2021 correctly.
Well, as it's the 4th today, there are no earlier events listed to show the effect. I tried to make the module list "incl. past events", but it did not show any.
Best regards
Stefan
