Hi again

Our wedding is Friday July 13. My fiance does not want to word the invitation the formal way "Friday, the Thirteenth of July" because he doesn't want it to clearly state the phrase Friday the 13th.
He prefers it to say "Friday, July Thirteenth" and on the next line "Two Thousand and Twelve".
The wedding is formal. Which wording is better or is either ok? I prefer the more formal wording.
Thanks!
