Scheduling a call between CST 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) overlap on January 15 from 9:00 AM to 2:00 PM in CST, which is 12:00 PM to 5:00 PM in BRT.

On July 15 the overlap runs 9:00 AM to 3:00 PM in CST (11:00 AM to 5:00 PM in BRT).
