Should You Use Words or Numbers for Dates?
Is it "the 27th of December" or "the twenty-seventh of December"?
Peggy N. asked, “It's the 21st. You have plenty of time. Do I write it that way, or should it be It's the twenty-first?
I like it better written out, but want to be correct.”
Whether you use arabic figures (21st) or words (twenty-first) is a matter of style, so if Peggy is writing it for herself, she can write it out in words if that’s what she likes.
Liking it written out makes her a Chicago Manual of Style type of girl because that’s what Chicago recommends. (1)
The Associated Press’ AP Stylebook, on the other hand, recommends using the arabic figures. (2, 3) Here’s a recent example from a New York Times article: “We’re hoping we’re going to be busy on the 24th, too.”
