National Punctuation Day In class today, I asked how many had celebrated the big event yesterday. Most looked puzzled as they were trying to decide what they’d missed.  But quite a few called out: “National Punctuation Day.” I discovered the event when I developed online grammar resources for the course Web site. The National Punctuation Day Web site includes rules about punctuation use and promotes Sept. 24 as National Punctuation Day.  In a recent lecture, I’d shown the class the list of resources and visited several of the grammar sites, including National Punctuation Day. I hope the ones who remembered the event also remember some of those punctuation rules. To get into the spirit of the day, I wore a National Punctuation Day T-shrit yesterday. The National Punctuation Day Web site offers a selection of T-shirts and other products. I went with the sun and the ellipsis rather than the T-shirt with “A semicolon is not a surgical procedure.”
