After limited events in 2020-2021 due to the COVID-19 pandemic, the date for 2022 onward was changed to the third Friday of May, to match the nation-wide practice.

A wide variety of bicycle-related events are organized throughout the Bay Area including "Neighborhood Rides" and "Energizer Stations" providing free food and coffee to bicycle commuters.
