When does NVC schedule interviews for GUZ/GZO

[pbz 11]

We did electronic processing and our case was completed at the NVC on Feb 25, 2016 and today (Mar 3), I received an email attachment which states the following:

The National Visa Center (NVC) received all the requested documentation for this immigrant visa case. The applicant is now in the queue awaiting an interview appointment overseas, where a consular officer will adjudicate the applicant’s visa application.

NVC schedules appointments one month in advance. The U.S. Embassy or Consulate General tells us what dates they are holding interviews, and NVC fills these appointments in a first-in, first-out manner. Most appointments are set within 60 days of NVC receipt of all requested documentation. However, we cannot predict when an interview appointment will be available.

I've read elsewhere on VisaJourney that NVC schedules interviews and sends out interview letters on specific weeks of the month of specific consulates/embassies. Does anyone know which week in each month NVC schedules interviews for Guangzhou (GUZ/GZO)? How long after the case complete can I expect the interview to be scheduled for?
