I have a event page, where it has the following items.

1. Event Name
2. Venue Name(s) {some cases go upto 5 or more venues}
3. Event Info {Genre(s),Language,type(s)}
4. Date(s) on which the event is.
5. Event Description.

Since, the Event name is unique, and present in the title, I am assigning <H1> to it.

However, venue names are multiple, plus the same venue may be repeated across the page, along with dates.

(Each)Event Info, is used a single time on the page Dates, are descriped in a styled manner using multiple spans, however, I am going to use a title on them.

Event description is in <p> tag.

So My question is which heading tags to use for a good symentic description and SEO.
Also the title on the dates, which format should I keep the date in? (dd/mm/yyyy)?
