I got a question for you: In Brazil, due to the Law of Directives and Bases of Brazilian Education, the academic year must have 200 days, both at schools and at universities. The school year usually begins during the first week of February. There is a 2-week / 4-week long winter break in July. The Brazilian school year ends the first week of December, summer in Brazil.

Based on this passage, when does the school year start in brazil?
Let's think first:
The relevant information to answer the above question is: The school year usually begins during the first week of February.
Therefore, the answer is the first week of February.
