This problem can be solved using the permutation formula since we are arranging 5 unique items (people) out of 12 (months). The formula for permutations is P(n, r) = n! / (n-r)!, where n is the total number of items, and r is the number of items to arrange. Here, n = 12 (months) and r = 5 (people), so P(12, 5) = 12! / (12-5)! = 12! / 7! = 12 x 11 x 10 x 9 x 8 = 95,040.
