It is noon when both the clock's hands are on twelve and the sun is overhead.
On a formal invitation, you would write "12:00 p.m." or simply "12:00 noon" to indicate twelve noon. It is best to avoid using "12:00 AM" or "12:00 PM," as they can be confusing. For added clarity and formality, you might also consider spelling it out as "twelve o'clock in the afternoon."
