On May 11th, all South Carolina state agencies were closed, as were government in ten counties, and one school district. I bet that really burned some folk. May 10th as Confederate memorial Day was part of a South Carolina compromise that also made Martin Luther King's birthday a permanent holiday. This year, May 10th was on a Sunday, so it was observed Monday.
May 10th was chosen because it was the day of Stonewall Jackson's death and the capture of Confederate President Jefferson Davis.
