Valentine’s Day followed by Presidents’ Day followed by Mardi Gras. It’s just party, party, party this week! I know you people. You’re wondering which is correct: “Presidents’ Day” or “Presidents Day.” After two minutes of exhaustive research on the internet, I’ve concluded that both are widely used, and it comes down to style and practice. Probably, “Presidents’ Day” is more widely regarded as proper. “President’s Day,” by the way, is a distant third.
