The first quarter in which a NH can meet this requirement is the 09/52 quarter (since
there must be at least six continuous QCs after 1950 and before that quarter). Thus,
the first day on which a freeze can begin under this requirement is 07/01/52, and
the last day on which it can begin is 12/31/55.
The first month for which we could pay a DIB based on this alternate test is 10/60.
(However, if the NH had not attained age 50 in or before 10/ 60, entitlement could
not begin before 11/60.)
