The questions should be asked of the head of household, spouse of the head of household or other adult household member if both head and spouse are absent.
What is ..[NAME]..'s day of birth?
Try to get the exact date of birth for each person, and the correct birth dates for children less than five years of age is very important. If the date is not known, ask if the animal sign of the Buddhist/ Cambodian calendar is known. If the animal sign is known, then use a conversion table to calculate it into the Western date (Gregorian date). If the respondent doesn't know the animal sign, try to ask him/her to remember the age in uncertain cases by comparing or matching it to any historical event possible listed. Sometimes the respondent apparently remembers that, he/she/other household member was born in coincidence with the event (occur at the same time).
Note: Please write '-' in column 4a (day), '-' in column 4b (month) '-' in column 4c (year) if the respondent do not know "the day, month or year". This information would help in entering age in column.5. The age conversion table and list of historical events are included in the last page of the manual (Khmer version).
