Substantially throughout any part of any calendar year
Substantially throughout any part of any calendar year means that any period you were not living with the child during a calendar year did not exceed 3 months. If the child was either born or attained age 3 during the calendar year, the period of absence in the year cannot have exceeded the smaller period of 3 months, or one-half the time after the child's birth or before the child attained age 3.
