College class reunions are the heart of the Alumni Weekend experience each spring. You’re welcome any year—but every five years your class is invited to a special milestone celebration, from your 5th Reunion to your 55th. (The College’s most recent grads also return for a special 1st Reunion gathering.) In 2021 we celebrated reunion classes from 2020 (those ending in 0 or 5) and the 2021 reunion classes (those ending in 1 or 6).
