Suggestions for the best way to do something

Have project that I am working on that is driving me mad, so I thought I would try and get some suggestions from you all.
What I need to achieve is a training schedule with trainers.
So each Trainer would have 6 trainees for a period of 6 weeks every saturday morning 9am - 11am
Ideally I would like to get this to show in a calendar, however when I add the start date and end date it gives a continuation of the event through mon, tue etc
I only want this to show on a saturday. Does anyone have any suggestions to make this work ?
