We run a theatre site for Washington, DC. People from around the world check our site to see what is on stage when they will be in DC. So they need to be able to indicate their available dates:: from and to, or start and end, as we indicate here. http://dctheatrescene.com/shows-playing/?allshows=1 (Note the date range isn't working in this example!) This one factor is preventing me from using your app for our WP site.
