Summer vacation is in July and August, and these two months have 365,438+0 days, respectively divided by 7 equals 4+3, so two months have 4+4=8 weeks, which is 8 times, and then two three days add up to a week, which is 9 times!

Many people, including myself, thought 0.8 times at first! I read my sister's counseling materials and worked out the answer myself.
