On National Coffee Day, we are reminded that anyone in this day and age can establish whatever celebration he pleases, so long as he has a Facebook account and a few friends with a bit of time to kill.
But they're not all merely frivolous: some are downright backward, like October 16's Boss's Day, or bafflingly unnecessary (e.g. Sandwich Day, Nov. 3rd - was ever there an object that required less public celebration?).
Suddenly parsnip day doesn't seem so very foolish. At least it was only a name, not a command.
