I have the same problem. My “events” are multi-day workshops. A single event might consist of “6PM to 9PM” on Friday, then “9AM to 4PM” on Saturday, and finally “9:00AM to 3:00PM” on Sunday. This is a single workshop with a single description, etc. I guess I could enter custom fields in the admin event-editor, one custom field for each day: “day-one-hours” would have value “6PM to 9PM”, etc.
Then I’d have to edit “single-event.php” to interpolate an array of the per-day hours. This seems like a common enough use case that it should be officially supported…
