Hey @Roberto!
Thanks for reaching out 🙂
You can achieve this in two ways, basically – first is to just create one event that starts on August 16th and ends on August 23, then in the event content itself just list what the sessions are via text.
The other method is to use the “Custom” recurring event type – if your events all happen within one week, then you can set the “Frequency” to “Weekly” and check each day that the event will happen, like shown in this screenshot:
This latter option is still not 100% what you’re looking for, but should get pretty close.
I should also mention that our next version of The Events Calendar PRO is coming with some better free-form recurrence, so that you can choose “non-normal” patterns like the one you mentioned here. That release is coming very very soon!
