On a "prime date," both the month and the day are prime numbers. For example, Feb. 7 or 2/7 is a prime date. How many prime dates occurred in 2007?

 You can easily eliminate the months: January, April, June, August, September, October, and December.

And, 2007 was not a leap year, February-9 dates, March-11 dates, May-11 dates, July-11 dates, November-10 dates.

If you add all the number together, you get an answer of \(\boxed{52}.\)
