Perfect Table Inspiration

P.S.- Ordered our invitations and thank-you's. You won't be seeing them for a while, but get ready! They are perfect!!!

So, we are trying to order our invitations, but can't decide what time. We want the ceremony to be during the day, ending with a sunset then night reception. I can't figure out the farmer's almanac. Wedding at 6 or 6:30? 7?
When does it get dark May 1st, 2010, in St. Francisville, LA?
