When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Korea Standard Time and Brasilia Time don't overlap on the same weekday. Brasilia Time is 12 hours behind Korea Standard Time.

With some flexibility, there’s a workable window outside standard hours:

  • 7 PM–8 PM in Korea Standard Time (7 AM–8 AM in Brasilia Time) — suggest 7:00 PM Korea Standard Time (7:00 AM Brasilia Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Public holidays in 2026

National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
