Q:

Dear 100 Hour Board,

What is the origin of the expression "never/not in a month of Sundays"? It means infrequently if at all, as in "You won't see that again; not in a month of Sundays".

- Odin

A: Dear Odin,

From the OED: "Phrase a month of Sundays 'a very long time' is from 1841. Roughly 7 and a half months, but never used literally."

From wordwizard.com: Apparently it originated in the United States. "It might be linked to the late 17C proverb 'when two Sundays come together', i.e. never."
