Writing to São Paulo from an Indian desk
São Paulo keeps UTC−3 all year. Brazil stopped changing its clocks in 2019, so the gap to India never moves: São Paulo is eight and a half hours behind IST in January and in July. A 10 a.m. meeting on Avenida Paulista is 6:30 p.m. in Pune or Chennai.
The US International Trade Administration describes a Brazilian office day of roughly 9 a.m. to 6 p.m. and suggests late morning, 10 to 12 local time, for calls with executives; it adds that in São Paulo itself, appointments run through most of the day. For an Indian team that means São Paulo replies arrive from early evening until well after midnight. Decide before launch who answers them, and schedule broadcasts in São Paulo time rather than IST.
The Indian consulate estimates the Indian community across Brazil at about 3,000 to 3,200 people, mostly in commerce, with São Paulo the first city it names. It is a small audience; most of the people you will write to in the city are Brazilian, and the first template you need is in Portuguese (Brazil), code pt_BR.
