A day off?

I'm very bad at remembering when my company has a holiday and when we do not. I thought that, just maybe, we had today off for Martin Luther King Day, but we don't. Apparently — I had to ask my dad — we used to have it off. But, as of this year many of the days that we used to get off have been converted to floating holidays (synonymous in almost every way with "vacation day"). So, I don't get today off.
