[BUG] Calendar events can not be created in german profile language

[wiihaa]

Describe the bug

When I change the user language to german i can not create events. While creating an event, i get a message that says 'event created successfully' but the event does not appear in the calendar overview.
When i change the language to english(US) it works perfectly.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'My Profile'
2. Change Language to 'Deutsch'
3. Go to 'My Calendar'
4. Create an Event
5. Event not showing in Calendar (event was not created)

Expected behavior
I would expect, that the event was created and visible in the Calendar
