I am using Afghanistan DHS 2015. Could anyone please help me to understand the date of interview (CMC) such as 1131. The variable name is v008. The recode manual describes that v008 was created by v006(month) v007 (year). V008 has 9 categories and values range 1131-1139, which is calculated in the Century Month Code.

To calculate the month and year from the CMC use the following formulae:
YYYY = int((CMC - 1) / 12)+1900
MM = CMC - ((YYYY-1900) * 12)

so, if I want to calculate the year from date of interview (v008)=int(1131 - 1) / 12)+1900=1994, which means the date of interview was 1994! AfDHS says that the data collection took place from 15 June 2015 to 23 February 2016.

The dates in the Afghanistan survey were all based on the Afghan calendar. The Century Month Code in this survey has a base year of 1300, not 1990. Thus the survey year was 1394 in the Afghan calendar.
