12:00 am CST is not suitable to schedule meetings
When planning a call between Central Standard Time and Central Daylight Time, you need to consider time difference between these time zones. CST is 1 hour behind of CDT.
It is currently 12:00 am in CST, which is not a suitable time to arrange a call or meeting with someone in CDT, since it is 1:00 am there, which not within the optimal time span between 7:00 am and 11:00 pm.
You could, however, schedule a call between 6:00 am and 10:00 pm your time. This time span will be between 7:00 am and 11:00 pm in CDT.
