MV Identification During Summer

When does everyone consider a student to be MV eligible if they first become eligible for MV during the summer? For example, if a student became homeless 7/2/20 when do you enter them in your MSDS as MV? Is it the day school begins? The day staff return? Another day?

What if the student was homeless on 7/2/20 but becomes permanently housed on 8/22/20 before school begins. Would you count them MV for the school year? Reason I ask this question is because according to Schoolhouse Connection they say you can count them. https://www.schoolhouseconnection.org/when-is-the-official-start-date-of-mckinney-vento-eligibility-for-homeless-children-and-youth-july-1-the-first-day-at-each-individual-school-if-a-school-starts-on-august-23-what-happens-to-student/
