Hi Pumice,
Thanks for checking out our plugins!
The recurring events feature of Events Calendar Pro will let you create events that recur at whatever upcoming date/time you specify, and you do have the ability to set multiple rules for one event.
So for July 21-22, you would create one event for the first day at 10am, then set it to recur the next day (at 10 am or at a different time).
We do offer full refunds within 30 days of purchase, so if you’d like to take Events Calendar Pro for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
