at the Academic Mall, allowing students to take a break from their studies and come together for social activity. First-year students are assigned a book written by a notable figure, who speaks to the entire freshman class on Commons Day in the fall semester. Commons Day speakers have included Supreme Court associate justice Sonia Sotomayor, author Janet Mock, designer Joshua Davis and journalist Charles M. Blow. The Festival of Lights started in 2000 as an annual Stony Brook tradition that celebrates the numerous cultures and faiths which celebrate during the holiday season. The festival is preceded by "Light the Brook", a tree lighting ceremony at the Academic Mall. Midnight Breakfast takes place during the first Monday of Finals Week in both semesters as the dining halls open late to serve breakfast foods to students. To celebrate Earth Day, Stony Brook holds a week-long Earthstock celebration in the week leading up, culminating in the Earthstock Festival. Numerous environment-themed events take place throughout the week, with the most known tradition being the Rubber Duck Race held at "The Brook" adjacent to the Administration building. Starting in 1993, Strawberry Fest is held on the first Wednesday of May, where students and faculty gather at the Academic Mall to eat an array of strawberry-themed foods with live music and student performances. In 1998, Stony Brook began to hold Diversity Day during the same day as Strawberry Fest, planned and organized by the Office of Multicultural Affairs to highlight the diverse cultures which make up the university. The yearly Roth Pond Regatta, held since 1989, attracts dozens of competitors and thousands of attendees, including students, faculty, staff, and alumni. The competition involves groups making boats out of cardboard and tape, with the challenge to get across the Roth Pond first without sinking. Stony Brook holds two annual concerts – Back to the Brook during the fall semester and Brookfest during the spring semester. The inaugural Back to the Brook took place in 2012 and featured Reel Big Fish at the Staller Steps. Since then, Mac Miller, Lupe Fiasco, Walk the Moon, Fetty Wap and Post Malone have headlined Back to the Brook. 2018's Back to the Brook was infamously cancelled after only 24 tickets were sold for headliner Ashanti a week before the concert. 2019's Back to the Brook was controversially cancelled again. The historic Stony Brook concert series was revived in 2011 with Brookfest
