The h1 element is the main title for the page, or section of the page it occurs in. Technically divs don't make a new section of the page. So If you are going to make this the main title of the page and make it look different than theother h1 elements you have on the page, then you can leave it. If it is supposed to be styled similarly to Date and Time, and Location, then I suggest changing them all to h2 OR changing the divs around those sections to a `<section></section>` element. 

I would also suggest giving a class that is the same to all of those elements (whether you keep div or change to section) on the page (conference, date, location, map, directions). This will make styling and other things easier.
