Field Offices on the Saturday schedule

As of July, 2002, most of the larger DMV offices are now open for Saturday service once a month (usually the third Saturday of the month). This will allow customers who have difficulty getting to an office during Monday through Friday the option of visiting the DMV on a Saturday from 8 a.m. to 12 p.m. As part of these new hours, these DMV offices will be closed on the Monday immediately preceding the Saturday service. These offices will open earlier and close later on the Tuesday – Friday of the same week.

Welcome to California indeed. They do, to their credit, include a handy chart to print out and scratch your head at.
