Scheduling a call between SAST and MST
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: daytime in South Africa Standard Time falls outside the working day in Mountain Time, so one side needs an early morning or late evening.
On July 15 standard business hours do not overlap at all.
