Ash Wednesday.
The inverse of "today is Thursday if yesterday was Wednesday" would state that if yesterday was not Wednesday, then today is not Thursday. Essentially, it negates the original conditional statement by asserting that the absence of Wednesday as yesterday implies that today cannot be Thursday.
If today is Wednesday it will be Saturday 136 days (19 weeks and 3 days) from today.
Also Wednesday 7 x 17 = 119
