WAT to MST hour by hour
Two columns because the gap changes with daylight saving: use the January column roughly November to mid-March, the July column mid-March to October. Exact switch dates vary by year.

Scheduling a call between WAT and MST
Standard business hours (9:00 AM to 5:00 PM) do not overlap in January: daytime in West Africa Time falls outside the working day in Mountain Time, so one side needs an early morning or late evening.
In July the overlap runs 4:00 PM to 5:00 PM in WAT (9:00 AM to 10:00 AM in MST).
