I’m sure you all know that a calendar is the kind of chart thingy with the days and months of the year divided up. You’re probably also aware that it’s very easy to type calender instead (you will be if you’ve read any of my drafts as I’m always doing it)

Did you know a calender is a real thing?

A calender is machine which uses rollers to press paper or cloth into smooth sheets. (The cat is sat on my slightly rumpled quilt, which is the closest photo I had. No, I won’t be producing an illustrated dictionary!)
