Saint Lucia is 1 hour behind Brasília right now. When it is 12:00 in Brasília, it is 11:00 in Saint Lucia. And it stays the same all year.
How many hours apart today
To find the time in Saint Lucia, subtract 1 hour from the time in Brasília. Saint Lucia follows America/St_Lucia (UTC-4), while Brasília is on UTC-3, so it is earlier there: when it is 12:00 in Brasília, it is 11:00 in Saint Lucia.
Until 01:00 in Brasília it is still the previous calendar day in Saint Lucia.
Daylight saving time: does the gap change?
No. Under current rules neither Saint Lucia nor Brazil changes its clocks, so the difference of 1 hour 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 10:00 to 18:00 Brasília time (09:00 to 17:00 in Saint Lucia), about 8 hours of overlap.
From Brazil, when it is 09:00 in Brasília, it is 08:00 in Saint Lucia (early, but reasonable); at 12:00 it is 11:00 (within office hours); and at 18:00 it is 17:00 (within office hours).
In the other direction, a call made in Saint Lucia at 9:00 reaches Brasília at 10:00 (within office hours); at 12:00 it is 13:00 there (within office hours); and at 18:00, 19:00 (late in the day, still reasonable).
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.
