(3) Commences or resumes on the first day of the month in which the child later becomes or again becomes incapable of self-support because of a mental or physical disability incurred before age 18 (or a later recurrence of such disability), if any lump sum is returned to the Fund.
(b) An annuity under this subpart terminates on the last day of the month before the child—
(1) Becomes 18 years of age unless he or she is a student as described in § 843.410 or is incapable of self-support;
(2) Becomes capable of self-support after becoming 18 years of age unless he or she is a student as described in § 843.410 ;

For accrual purposes, the last day of a 28-day month constitutes 3 days and the last day of a 29-day month constitutes 2 days.
