Hey, how many months?

Today while walking to the metro from a meeting with a possible new client, I was stopped and asked for directions to Chinatown. I answered as best I could, and then the guy asked me the above question. I couldn't help it. I squealed at him, "You're the first person to ask me that!" and gave the answer of five months. He wished me well and walked off. Then I realized that the correct answer is actually six months. But at least I pointed him in the right direction to Chinatown.
