How Much Time Does a Classroom Teacher Have to Teach?

In the United States, schools do 180 days of classroom instruction per year. That's fairly common on a global average within kind of the Western European nations. So if you multiply 24 times 25, you wind up with 600 hours. And so they estimate that Spanish is a 600 class hour language. Also included in this category would be language like French, which they say is a 30 week language.
