Sri Lanka is 8 hours 30 minutes ahead of Brasília right now. When it is 12:00 in Brasília, it is 20:30 in Sri Lanka. And it stays the same all year.
How many hours apart today
To find the time in Sri Lanka, add 8 hours 30 minutes to the time in Brasília. Sri Lanka follows Asia/Colombo (UTC+5:30), while Brasília is on UTC-3, so people there are already living further into the day: when it is 12:00 in Brasília, it is 20:30 in Sri Lanka.
Note that the gap is not a whole number of hours: the zone uses a UTC+5:30 offset, so the minutes change too, not only the hour. When you convert, keep the 30 extra minutes in mind.
From 15:30 in Brasília it is already the next calendar day in Sri Lanka.
Daylight saving time: does the gap change?
No. Under current rules neither Sri Lanka nor Brazil changes its clocks, so the difference of 8 hours 30 minutes holds all year round: a meeting fixed at the same Brasília time lands at the same local time in every season, with no need to recheck in March or October. Brazil abolished daylight saving time in 2019, and it only matters for the gap when the other country changes its clocks. See the daylight saving time guide for the countries that do.

Best times to call or hold a meeting
Assuming 9:00-18:00 office hours on both sides, the shared window runs from 09:00 to 09:30 Brasília time (17:30 to 18:00 in Sri Lanka), about 30 minutes of overlap. That is a short window, so book it early and keep meetings tight.
From Brazil, when it is 09:00 in Brasília, it is 17:30 in Sri Lanka (within office hours); at 12:00 it is 20:30 (late in the day, still reasonable); and at 18:00 it is 02:30 (next day) (night or very early, best avoided).
In the other direction, a call made in Sri Lanka at 9:00 reaches Brasília at 00:30 (night or very early, best avoided); at 12:00 it is 03:30 there (night or very early, best avoided); and at 18:00, 09:30 (within office hours).
The same arithmetic helps with flights, whose departure and arrival times on tickets are always in the local time of each airport, and with live broadcasts announced in another time zone. Always convert the announced time before you plan. The meeting planner compares both clocks hour by hour.
