"""Determines whether or not the match is valid during all weeks of the
schedule. Even though the match will definitely be valid on
earliest_course_start_UTC, it is possible that the student or tutor will
no longer be able to make the course if daylight saving occurs for the
student or for the tutor as the course progresses. Also, some of the

daylight saving.
Returns:
A boolean whether or not both the student and the tutor can make
