Invitation Capitalization?

[thomastaci22]

Hey girls! We are putting together the wording for our invites to our wedding...finally! But I can't figure out what words should or shouldn't be capitalized?? For example...

 

...on the Nineteenth day of September two thousand and eight at eleven o'clock in the morning...

 

 

Is that correct? Or is the year capitalized? The time? The day? HELP!!

Our wording on the invitations are:

 

Saturday, the eighteeth of October, two thousand and eight at four o'clock in the afternoon.

 

I think I may have gotten this from reading other invites. I hope this helps!!
