Business hours and meeting times
Comparing a 9:00–18:00 working day in IST against 9:00–17:00 in Sao Paulo, across the whole week — a slot only counts if it lands on a working day at both ends.
Both sides work Monday to Friday, so the working weeks line up and you share 5 days.
Rows are days in IST. Columns are hours of the IST day.
No standard overlap
A 9–6 day in IST never meets a 9–5 day in Sao Paulo on any day of the week, so one side has to move outside normal hours. Ranked by how far outside:
- 5 PM IST = 8:30 AM Sao Paulo — needs about 30 minutes of stretch
- 4 PM IST = 7:30 AM Sao Paulo — needs roughly 1 hour and 30 minutes of stretch
- 3 PM IST = 6:30 AM Sao Paulo — well outside normal hours — 2 hours and 30 minutes beyond
These hold on every shared working day (5 a week). Teams working this gap regularly tend to alternate which side takes the early or late call, and keep the synchronous meeting short.
Public holidays
A shared working day is only usable if neither side is on holiday — and India and Sao Paulo build their calendars on different systems, so the days each loses rarely coincide.
Over the next 8 weeks you share 40 working days. 4are lost to a public holiday on one side or the other, leaving 36.
| Date | Who is off | Holiday |
|---|---|---|
| Friday, October 2, 2026 | India | Gandhi Jayanti |
| Monday, October 12, 2026 | Sao Paulo | Our Lady of Aparecida (Nossa Senhora Aparecida) |
| Tuesday, October 20, 2026 | India | Dussehra (Vijayadashami) |
| Monday, November 2, 2026 | Sao Paulo | All Souls' Day (Dia de Finados) |

India has three national holidays on which the whole country closes. Everything else is either a central-government gazetted holiday that individual employers choose to observe, or a state holiday. Festival dates follow lunisolar calendars and move every year, so they are listed explicitly rather than derived.

Frequently asked questions
What is the time difference between IST and Sao Paulo?
Sao Paulo is 8 hours and 30 minutes behind IST, on every date of the year. Neither side observes daylight saving time.
What time is 9 AM IST in Sao Paulo?
9:00 AM IST is 12:30 AM in Sao Paulo, all year round.
What is the best time for a meeting between IST and Sao Paulo?
Standard working days do not overlap at all in this pair, so somebody has to stretch. The closest slot is 5 PM IST / 8:30 AM Sao Paulo — it needs about 30 minutes of stretch. Teams that meet regularly across this gap usually alternate who takes the awkward end.
Does India observe daylight saving time?
No. India has kept a single UTC+5:30 offset since 1945 and does not use daylight saving time, so IST reads the same on every date of the year. Any change in the gap to Sao Paulo comes entirely from the other side.
How many hours a week do IST and Sao Paulo actually overlap?
None at standard hours. A 9–6 day in IST does not meet a 9–5 day in Sao Paulo on any day of the week, so a recurring call means one side works early or late — the section above ranks the least disruptive options.
Do public holidays in IST and Sao Paulo line up?
Barely. Over the next eight weeks the two sides share 40 working days, and 4 of those are a public holiday on one side or the other, leaving 36. The next holiday in Sao Paulo is Our Lady of Aparecida (Nossa Senhora Aparecida) on 2026-10-12. Indian, Gulf and Western holiday calendars are built on different systems, so the days each side loses rarely coincide.
Is IST ahead of Sao Paulo?
Yes. IST runs ahead of Sao Paulo by 8 hours and 30 minutes, so a working morning in IST lands the previous evening or night in Sao Paulo.
