Let's talk about the daily grind and special vocabulary

The first day of school varies in different areas around the world because of the differences in weather, climate, season, and culture. However, the normal pattern is for school to begin in late August or early September in the northern hemisphere and in late January or early February in most Southern Hemisphere countries.

In the United States, for many school districts in various states schools opens on the day after Labor Day (first Monday in September). On that day, public transportation services increase and start the rush hour earlier. 

So, September has arrived. For many people this signals the end of the summer holidays and the return to the daily grind ( the everyday work/school routine).
