Qualifying Student Dependent

My son was 23 yrs old as of Sept 15, 2020. He started colloeg in the Fall of 2020 and took a full load by the college's standards. The calender term for that semester was 8/17/20 - 12/18/20 (4 mths). I supplied more than half his financial support for that period. Can I claim him as a dependent for 2020?
