Scheduling a call between IST and BRT
The examples assume 9 AM to 5 PM on a working day in both places. They do not check weekends, local holidays, or individual schedules.
Standard business hours (9:00 AM to 5:00 PM) do not overlap on January 15 and July 15: daytime in India Standard Time falls outside the working day in Brasilia Time, so one side needs an early morning or late evening.
