Only display the day once for one day events

Problem to solve

Currently the dates of the event are displayed like this "Fri. 18th December, 2020 14:00 - Fri. 18th December, 2020 15:00". This is hard to get at a glance.

Proposal

If it is a one day event it would be nice to have it like this: "Fri. 18th December, 2020 14:00 - 15:00"

Acceptence Criterias

For one day events the event day is only shown once
For multi day events the days are still both displayed
