Both grammatical structures are correct, however in AmE we would write the date as March 3, 2013 or March 3rd 2013. It is possible to use a comma after 3rd. When speaking, we would say March third or March the third. There are many variations in both AmE and BrE.
I'm not sure what you mean by to be to be. Your example, to be held, is a passive infinitive and is commonly used in notices and announcements. See section 97/2 in Swan's Practical English Usage (1984).
