Add weekday to newsletter events

In the current newsletter, there is only a date and time next to the event. It would be nice if there also was a (week)day there, because most people plan activities based on what day they are.

One-sentence description

Add the event day to events in the newsletter.

Motivation

This change would make it more easy to plan events if you just read the newsletter from time to time.

Desired functionality

Add the (week)day to the event info in the newsletter.
