Learn Math with Annoying Teacher

I love math, and I learn math every wednesday and friday, but unfortunately, I have an annoying math teacher. He always choose a student who has absent number equal to the date to answer a hard question in front of the class. (For example : If the date is January 1st, 2016 he will choose a student who has 1st absent number) If my absent number is 24, How many times he will choose me in 2016 ?

Hint : January 1st, 2016 = Friday
