Hi @Dominik,
This would generally be possible using the recurring events system in Events Calendar Pro, with an event configuration like the one shown in this screenshot (click for a larger-sized image):

However, there is currently a bit of a bug with same-day recurrence patterns like this. ๐
So your best bet would probably be to make three separate recurrence series. Each one should start on May 16 and end on May 28, and should have an “Exclusion” set up for every Monday so that Mondays don’t have events. Make the first series be for the 11โ13 event, then another one for the 16โ18 event, and then another for the 20โ22 event.
I hope this helpsโand sorry to bear news about the bug!
