Why people convert São Paulo to Colombo time

Scheduling a call from São Paulo to Colombo: a 10:00 AM start in São Paulo lands at 6:30 PM in Colombo, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h 30m gap: São Paulo and Colombo have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Colombo is 5:30 PM in São Paulo.
Booking travel or deliveries: tracking Colombo local time against São Paulo keeps pickup windows and arrival estimates honest across the +8h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +8h 30m gap is not.
With a +8h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week São Paulo takes the early slot, the next week Colombo does.

About BRT (Brasilia Time)

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.

About IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh.

India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.
