# §436.522. Determination of age.

- (a) In determining age, the agency must use the common law method (under which an age is reached the day before the anniversary of birth) or the popular usage method (under which a specific age is reached on the anniversary of birth), whichever is used under the corresponding State plan for OAA, AFDC, AB, APTD, or AABD.
- (b) The agency may use an arbitrary date, such as July 1, for determining an individual's age if the year, but not the month, of his birth is known.
