Shared working hours
They do not overlap at all. A 09:00–17:00 working day in Brasília Time ends 30 minutes before the India Standard Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in BRT against late evening in IST, or the other way round.
When the difference changes
It doesn't. India Standard Time is 8 hours 30 minutes ahead of Brasília Time on every date of the year. Brasília Time runs at UTC-03:00; India Standard Time runs at UTC+05:30.
About Brasília Time
Brazil abolished daylight saving in 2019, so Brasília Time has been a fixed UTC−3 ever since. Anything written before then — including a lot of still-published conversion tables — assumes a southern-hemisphere shift that no longer happens.
Cities on this clock: São Paulo, Rio de Janeiro, Brasília, Buenos Aires, Montevideo.
About India Standard Time
India keeps one clock, UTC+5:30, across a country spanning about 29 degrees of longitude — the sun rises nearly two hours earlier in Arunachal Pradesh than in Gujarat on the same clock. The half-hour offset means most conversions from India land on the half hour rather than the hour. Sri Lanka keeps the same time.
Cities on this clock: Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad.
Watch out: IST is also Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page is the Indian one.
How the difference is worked out
Neither Brasília Time nor India Standard Time moves its clock relative to the other, so india standard time is 8 hours 30 minutes ahead of brasília time is a rule rather than a fact about one particular year. The hour-by-hour table above holds on every date.
With both zones on their own standard time — daylight saving not in force anywhere — India Standard Time is 8 hours 30 minutes ahead of Brasília Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids America/Sao_Paulo and Asia/Kolkata. Nothing is looked up on a server and nothing about your visit is recorded.
