4. Age. With regard to the date, month and year of birth, the Gregorian calendar is recommended. If it is recorded in Lunar calendar, fill in the questionnaire as it is, and conversion is not needed. Complete years of age is counted from the date of birth to the reference time. Just write down the number of years as counted, leave out the months. For example, for a child who is two years, eleven months and twenty-nine days old, "2" should be placed preceding the printed characters of "years of age"; for an eight-month-old baby, "0" is put before the printed characters of "years of age". Those who only know their nominal age [pg. 22] or zodiac sign or the sexagenary cycle may work out their complete years of age in reference to the "Age Conversion Table". The date of birth and the complete years of age should be written in Arabic numerals.
