Miss Jas, a teacher whose birthday is M/D (where M is month, D is day) has two students, Joy and Wen.

Both students know that Miss Jas' birthday is one of the following:

2/15, 2/20,4/14, 4/15, 4/18,6/14, 6/17,8/2, 8/18, 8/20

Miss Jas told M to Joy and told D to Wen. She then asked the two students the question, "Do you know what my birthday date is?"

Joy says: "if I do not know, Wen does not know it either". Wen says: "I didn't know it at first, but now I know". Joy says: "oh, then I know it too now".

So what is Miss Jas's birthday date?
