Hyphens, En Dashes, Em Dashes

Q. When announcing a fundraising event, is it hyphenated or not? Stay at Home Tea or Stay-at-Home Tea?

A. There are no special punctuation rules for fundraising events. Your event title requires hyphens (as in the second example). However, if your event were called Golden Anniversary Tea, or Empty Nesters’ Tea, it would not. Please see the hyphenation table at CMOS 7.89 to learn more about when to hyphenate.
