The festivities begin at 11 a.m. Saturday, May 1, on the street in front of the new Oak Street entrance with a Native American Ohlone blessing, a marching band, Project Bandaloop performing a spectacular aerial dance, and more. And the non-stop celebration continues through 6 p.m. Sunday, May 2.

"Only in California" Saturday afternoon activities highlight the innovative and creative spirit of California.

Saturday evening and overnight activities take on a more adult flavor with dancing, live music, games, film,  food vendors, a cash bar,off-beat gallery tours, and conversations on uniquely California topics. Bring your PJ's and wake up to early morning yoga.

Sunday is especially for families with dancing, drumming, hands-on family activities, the Oakland Interfaith Gospel Choir, and more. The new expanded OMCA Store will be open the full 31 hours so visitors can shop whenever the mood strikes.

And of course the highlight of the 31 hours will be the excitement of discovering the story of California, the story of you, in the new Galleries of California Art and History.
