brazil is unique in the fact that the date selected to celebrate is actually steeped in history.

the 15th of october was the day that emperor pedro i institutionalized and created elementary schools for the poorer people of the country.

it wasn't until the late 1940s however that the first teacher's day was celebrated in the country and another 15 years before it was declared to be the holiday that we now know it to be. 

stores, offices, and public transportation operate at regular hours.
