5:00 am CT is not suitable to schedule meetings
When planning a call between Central Time and Mountain Time, you need to consider time difference between these time zones. CT is 1 hour ahead of MT.
It is currently 5:00 am in CT, which is not a suitable time to arrange a call or meeting with someone in MT, since it is 4:00 am there, which not within the optimal time span between 7:00 am and 11:00 pm.
You could, however, schedule a call between 8:00 am and 12:00 am your time. This time span will be between 7:00 am and 11:00 pm in MT.
