Official CDCR Custody Credits Guide
Posted: 5/16/16
This chart describes the credits that are actually being awarded by CDCR, including, for example 1/3 credits (one day for every two days served) for a prisoner sentenced as a second striker for a nonviolent offense (even though contrary to the Three Strikes law, but implemented to resolve prison over-crowding).
This chart provides instructions on calculating presentence conduct credit under Penal Code sections 4019 and 2933 in the Third and Fifth Districts.
