This day is dedicate to those who died in active military service. We remember them for their service and contributions to our freedom. Traditionally observed each May 30 it is now observed on the last Monday in May to accommodate the slackers of the workforce.
We in the deep South (and who are actual Southerners, mind you) have other such days marking the service of the Confederate forces (in the southern states) any of various days (particularly the fourth Monday in April) on which those who died serving in the Confederate forces are remembered. Known as Confederate Memorial Day there are presently two existing celebrations which are important to we who hail from South of the Mason Dixon line.
