Bug description

I have a recurring fortnightly calendar appointment for my pay day. I made it 11-ish months ago.

It's next due tomorrow. But on the dashboard, it's

1. Correctly showing up as an upcoming event, but
2. It's showing its date as "11 months ago".

I have a feeling this used to be correct? Unsure now I think about it though...

Steps to reproduce

1. Have a long running fortnightly recurring event in Nextcloud calendar, whose initial date is many months ago.
2. Go to dashboard.

Expected behavior

See its correct next/upcoming date in the "Upcoming events" Dashboard section.

I did try hard to find a duplicate issue first so I hope I didn't just miss one - apologies if I did.
