The DHS Program, which manages registration and access for IPUMS DHS, is again reviewing new user applications and requests for expanded access from currently approved users.
Codes
HHINTCMC (HV008) is a 4-digit variable.
Description
HHINTCMC (HV008) reports the century month code for the date on which the interview took place.
Century month codes (CMC) are particularly useful for checking the consistency of dates, calculating intervals between events, and imputing dates when the information for an event is missing or partially complete.
Century month codes (CMC) are calculated by multiplying by 12 the difference between the year of an event and 1900. The year 1900 was chosen as the reference period because all of the DHS-relevant events occurred during the twentieth or twenty-first centuries. The month of the event is added to the previous result.
CMC = (Year minus 1900) * 12 + Month
For example, the CMC for June 2002 is:
CMC = (2002 minus 1900) * 12 + 6 = 1230
In other words, 1,230 months have elapsed between January 1900 and June 2002. Starting with CMC figures, one can calculate the month and year using the following formulas:
Year = int( ( CMC minus 1 )/12 ) + 1900
[int(x) is the integer part of x]
Month = CMC â ( ( Year minus 1900 ) * 12 )

The century month codes reported in HHINTCMC are calculated using the Gregorian calculator.
Comparability
Apart from universe differences, HHINTCMC (HV008) is largely comparable across samples. While all samples in this variable utilize the Gregorian calendar, other samples utilize country-specific calendars and are excluded from HHINTCMC but are included in country-specific variables.
Comparability - Standard DHS
HHINTCMC (HV008) is included in the standard DHS questionnaire for Phase II forward.
