During World War II, the Army Signal Corps controlled the campus, and Picnic Day disappeared from 1943 to 1945. Since 1946, Picnic Day has been growing strong and now boasts an annual attendance of more than 70,000 people. This year, there will be more than 200 events on campus and an estimated 75,000 visitors attending this special event. Since 1959, the parade was extended to include downtown Davis to celebrate the fact that Davis became a separate UC campus and not just the Farm School for UC Berkeley.
