Definition
HHDOBCMC reports the century month code (CMC) for the household member's date of birth, according to the Gregorian calendar.
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.
For more information on how to calculate and interpret century month codes in general, see HHINTCMC (HV008).
