Formating Caldav-Event NAMEANDTIME

hi together…

i’m looking for a formatstring. In my items-file i have an entry like

String CMuellTermin “Muellabfuhr [%s]” {caldavPersonal=“calendar:Muellplan type:EVENT eventNr:1 value:NAMEANDTIME”}

which will display

Blaue Tonne: xxx @ 3/13/19 12:00 AM - 3/14/19 12:00 AM

but… i just need the information

13.03.2019:Blaue Tonne

How can i format the response correctly?
