MLK day is actually being celebrated on…..MLK day! It is, actually his birthday on the day it is celebrated instead of kinda-sorta close to that day…..
Usually it is just whatever Monday is closest so that Government employees and leeches (but I repeat myself) get a three day weekend……Which always seemed to me to weaken the impact and import of the holiday and doesn’t really honor the person that the holiday is supposed to honor.
Pick the day, and celebrate it when it actually happens. Or not. But the holiday isn’t just another excuse for a three day weekend.
