1 Answer. No, “Good Noon” is not commonly used. “Good Afternoon” is technically appropriate anytime after 12 noon. As an alternative, you could also say “Good Day”.

What greeting do you use at noon?

Good morning 5:00 AM to 12:00 PM. Good noon 12:00 PM to 2:30 PM. Good afternoon 2:30 PM to 5:00 PM. Good evening 5:00 PM to 8:00 PM.

How do you greet after 12?

7 Answers. Both “Good afternoon” and “Good evening” are perfectly appropriate greetings at 6pm. If you say “Good evening” at 4pm, or “Good afternoon” at 8pm, you might get funny looks, but near the boundary, either is fine.
