April Challenge 2

Not Cheryl's Birthday

Albert and Bernard were catching up one day in September.

"Do you have any kids?" Albert asked.

"Indeed I do," replied Bernard. "I have three daughters."

"What are their ages?" inquired Albert.

"Well, if you multiply their ages together, you get 36. Oh, and if you add up their ages you happen to get today's date."

"You are a jerk," said Albert, as he checked his watch for the date. "And I still don't know your kids' ages."

"Oh, did I mention that my oldest daughter loves math?"

"Well, why didn't you say so. Now I know the ages of your daughters."

The Challenge: What are the ages of Bernard's three daughters?
