BART trains do operate on holidays, but the service may be adjusted based on the specific holiday. Typically, during major holidays like New Year's Day, Martin Luther King Jr. Day, Thanksgiving, and Christmas, BART may run a reduced schedule compared to regular weekdays. It is essential for passengers to check the BART schedule for each holiday, as there may be changes in frequency and operating hours. While some holidays see service continuing throughout the day, others may have limited hours of operation. Therefore, it is advisable to look on the official BART website for the most current information regarding holiday schedules and any potential service changes. This will ensure that riders have the latest details for their travel plans.
