More than 30,000 visitors are expected to attend Cal Day on Saturday, April 19.

The centerpiece of the day is the Charter Anniversary Celebration featuring Chancellor Tien, Princeton President Harold T. Shapiro and Peter E. Haas, 1996 Alumnus of the Year.

The annual open house, which has become the campus's biggest annual event, showcases the wide spectrum of activity -- from compelling and far-reaching scholarship to arts and music and sports -- that makes the campus a Bay Area gem and a national education leader.

The event runs from 9 a.m. to 4 p.m. Nearly everything, including parking and museum admissions, is free.

The Charter Anniversary Celebration features traditional university music and a colorful academic procession replete with banners and regalia.

It will be held outdoors in Dwinelle Plaza beginning at 11 a.m.

The ceremony will feature an address by Tien and remarks by Shapiro.

Shapiro has been president of Princeton University since 1988 following a career at the University of Michigan which culminated in that university's presidency.

He is an economics and public policy scholar and was appointed chair of the National Bioethics Advisory Commission by President Clinton last July.

Robert Berdahl, who will become Berkeley chancellor in July after Chancellor Tien steps down following seven years at the helm, will attend the ceremony.

In addition, Venkataram Rama-krishna, director of urban health education in Bangalore, India, will be presented the Haas International Award.

Elsewhere and all day long, faculty, students and staff host a wide range of fun and provocative activities.

Because this is CyberSemester '97, a special web site, a Cal Day Scrapbook, is being created for the day with news and photos of Cal Day events posted as they happen. The campus's web site is www. berkeley.edu.

Other special events include a walking tour of the campus portion of the Hayward Fault, International House's SpringFest, a rare look at Lawrence Berkeley National Laboratory's Advanced Light Source and workshops and tours for new and prospective students.

Thirty-minute trolley tours of the campus, with guides providing highlights of campus life, architecture and history, will be offered free throughout the day.

Guests can eat at a number of campus restaurants and outdoor grills

A program with a complete listing of all activities will be available at campus entrances on the day of the event.

Dozens of lectures presented by the campus's expert faculty will explore compelling social issues and scientific discoveries.

Professor Bruce Ames will discuss "Understanding the Causes of Aging and Cancer" while Professor Geoff Marcy speaks on recent discoveries of new planets and Professor John Taylor prepares a variety of savory mushrooms as part of his lecture on edible fungi.

Sports fans can watch the football team scrimmage at Memorial Stadium, then meet the players and new head coach Tom Holmoe or try out their own rock climbing skills with free trials at Cal Adventure's climbing wall.

For children, storytellers from the Bay Area will offer tales of whimsy and intrigue at the Celebration of Children's Literature and they can build intelligent robots with Legos at the College of Engineering.

Also among the day's activities is the 23rd Annual Pacific Coast Collegiate Jazz Festival.

And if that's not enough, all campus museums, including the Lawrence Hall of Science, will be open with free admission.

Special tours are scheduled for the Berkeley Art Museum; the Botanical Garden's collection of exotic plants are on display with many currently in bloom and the mysterious world of bugs is featured at the Essig Museum of Entomology.

Limited free parking is available. Visitors are encouraged to take public transportation.

The campus is easily reached by AC Transit and is just one block from the Berkeley BART Station. Free shuttles will be available to take visitors from the BART station to various campus locations.

Shuttles are also available to take visitors up to the Lawrence Hall of Science and Botanical Garden.
