invitation wording...

The simplest things become tricky when writing out wording for an invitation.  Suddenly, we can’t remember basic grammar…We go back and forth-does the date have “and” in the year written out?  Is there a period after Miss?  How do you abbreviate a.m. and PM?

Here are some of the commonly  used/misused conventions.
