full time student interpretation

Hello

my daughter was 23 in 2024 and graduated in the university ceremony with a 4 yr degree on April 26...  5 days shy of May 1.  I understand that a full-time student means 5 months in school.  How rigid is this interpretation.  The university she attends used to have their ceremony in early May.  I would like to claim her as a dependent because I am still covering more than 50% of her expenses.
