My wife, born in 1963, remembers it from nursery school but we can’t find the book of any other references.
I’d buy the book on the spot if I knew it contained this phrase. It is sort of a grail quest at this point.

New format, same book stumper solving.
Is it possible she went to a religious school? The only reference I found for this phrase is: “Shut Door Day” refers to a specific, now-rejected, belief within early Millerite Adventism (mid-1840s) where followers thought salvation’s “door” closed after Jesus entered the heavenly sanctuary in 1844, meaning latecomers couldn’t be saved; however, this evolved into the modern Seventh-day Adventist Church’s “Investigative Judgment” doctrine about the sanctuary, not Earth, as they realized their initial “shut door” interpretation was wrong. It contrasts with the general idea of God closing doors as redirection, common in Christian thought.
The original concept came from the Parable of the Ten Virgins (Matthew 25), where the door was shut after the bridegroom arrived.
Hope that’s helpful.
