Title 18 › PART II — CRIMINAL PROCEDURE › CHAPTER 227 — SENTENCES › SUBCHAPTER D — IMPRISONMENT › § 3585
A prison sentence starts on the day a person is taken into custody to be moved to, or when they arrive to begin serving time at, the official jail or prison where the sentence will be served. A person must get credit for any time spent in official custody before that start date if that custody was for the crime they are being sentenced for, or for another charge they were arrested on after committing that crime, as long as that time was not already counted toward a different sentence.
