Federal Prison News · Release Dates and Time Credits
Is the Date on the BOP Inmate Locator His Real Release Date?
You typed his register number into the Bureau of Prisons inmate locator, and a date came back. You have looked at it more times than you would admit to anyone. Then somebody on the compound told him it was wrong, or it shifted by a few days and nobody explained why, or it has not moved at all through months of classes he keeps telling you he is going to.
The date is real. It is also not the day he comes home, and it was never the judge's number to give. The second half is usually the good news.
The judge imposed the sentence. The Bureau does the arithmetic.
This trips up almost every family, because the judge is the person you watched do it. The counting happens afterward, inside the prison system.
The Supreme Court settled that in United States v. Wilson, 503 U.S. 329 (1992). The Court held that "§ 3585(b) does not authorize a district court to compute the credit at sentencing," because "After a district court sentences a federal offender, the Attorney General, through BOP, has the responsibility for administering the sentence."
So when the number looks wrong, the place to take it is the Bureau, not the courtroom. And the arithmetic is written down in three pieces you can actually check.
The three pieces behind the date
1. The day the clock started. Under 18 U.S.C. § 3585(a), a sentence "commences on the date the defendant is received in custody awaiting transportation to, or arrives voluntarily to commence service of sentence at, the official detention facility at which the sentence is to be served." Not the day of the plea. Not the day of sentencing.
2. The time he already sat. Under 18 U.S.C. § 3585(b), he gets credit for time in official detention before that date, either "as a result of the offense for which the sentence was imposed" or from another charge he was arrested on after the offense — but only time "that has not been credited against another sentence." That last clause is the single most common reason your arithmetic and the Bureau's do not match, especially when a state case was running alongside.
3. Good conduct time. Under 18 U.S.C. § 3624(b)(1), a person serving more than a year may receive "up to 54 days for each year of the prisoner's sentence imposed by the court, subject to determination by the Bureau of Prisons that, during that year, the prisoner has displayed exemplary compliance with institutional disciplinary regulations." The statute also says plainly: "Credit that has not been earned may not later be granted."
Put those together and you have the Locator date. Under 18 U.S.C. § 3624(a), he is released "on the date of the expiration of the prisoner's term of imprisonment, less any time credited toward the service of the prisoner's sentence as provided in subsection (b)."
That is the whole formula. It is a projection, recalculated as facts change — which is why the date can move, and why a change is not automatically bad news.
What that date does not include — and this is the part worth reading twice
The Locator date is built on good conduct time. First Step Act time credits are a separate system, and they can move him out of the prison well before it.
Two different steps, and families mix them up constantly:
Earning. Under 18 U.S.C. § 3632(d)(4)(A), "A prisoner shall earn 10 days of time credits for every 30 days of successful participation in evidence-based recidivism reduction programming or productive activities," plus "an additional 5 days" per 30 days for someone the Bureau rates at minimum or low risk who, "over 2 consecutive assessments, has not increased their risk of recidivism." The regulation repeats the same math at 28 C.F.R. § 523.42(c), and § 523.42(a) says he begins earning only "after the inmate's term of imprisonment commences."
Applying. Earned credits "shall be applied toward time in prerelease custody or supervised release" under 18 U.S.C. § 3632(d)(4)(C) — but the applying has its own conditions, in 18 U.S.C. § 3624(g) and 28 C.F.R. § 523.44(b): he needs credits equal to the remainder of his imposed term, risk reassessments showing reduction or a maintained minimum or low risk, and the remainder of the term "computed under applicable law."
And it is permissive, not automatic. The statute says the Director "may transfer the prisoner to begin any such term of supervised release at an earlier date, not to exceed 12 months." Nobody should tell you it happens by itself.
The halfway house date is a third date
18 U.S.C. § 3624(c)(1) directs the Bureau, "to the extent practicable," to let him spend "a portion of the final months of that term (not to exceed 12 months)" preparing to return to the community, which "may include a community correctional facility." Home confinement under § 3624(c)(2) runs "the shorter of 10 percent of the term of imprisonment of that prisoner or 6 months."
So there are really three dates: the one on the screen, the day he leaves the institution, and the day supervision ends. The first one is usually the latest.
What to ask for today
Stop trying to reverse-engineer it from the website. Get the paper.
- Have him submit a written request to his case manager — an inmate request form, the cop-out — asking for a printed copy of his sentence computation and his FSA time-credit assessment. He is asking for records about himself. It is a normal request, and it is free.
- Check three things against what you know: the date his sentence commenced, the jail credit for time served before that, and the good conduct time.
- Have him keep his copy. You keep a copy. Every later step is built on the paper from this one.
If he is in a Special Housing Unit, in transit, on a writ to another agency, or on a mental-health hold, 28 C.F.R. § 523.41(c)(4) treats him as generally not "successfully participating" during that stretch — which is its own answer to the question of why the credits stalled.
This week, if the numbers are wrong
The fix is the Administrative Remedy Program — the remedy actually available to him from inside — and it runs on short clocks.
- BP-9 to the warden, due "20 calendar days following the date on which the basis for the Request occurred" (28 C.F.R. § 542.14(a)).
- BP-10 to the Regional Director "within 20 calendar days of the date the Warden signed the response," then BP-11 to the General Counsel "within 30 calendar days of the date the Regional Director signed the response." That last one is the end of the line: "Appeal to the General Counsel is the final administrative appeal" (28 C.F.R. § 542.15(a)).
- Staff have their own deadlines — 20 days, 30 days, 40 days, extendable once with written notice. And if the answer never comes, the regulation says "the inmate may consider the absence of a response to be a denial at that level" (28 C.F.R. § 542.18).
That last sentence rescues more cases than anything else on this page. Silence is not the end of the road. It is a denial he can appeal, on time, instead of sitting and waiting.
What to stop worrying about
That the date moved. Good conduct time is determined year by year, and a computation gets corrected when new information lands. Movement means someone recalculated, not that something was taken.
That the screen is a promise. It is the Bureau's current arithmetic, and nobody can tell you the exact day he walks out.
That you need to buy the answer. Every rule above is public, and his own computation sheet is his for the asking.

If you would rather just talk to a person, call 786-408-5073 and ask for Charles Christopher. If it is the middle of the night, send the email instead and it will be read in the morning.
Prisoner Legal Aid prepares documents, requests records, explains deadlines, and connects families with independent civil rights attorneys, under the oversight of a licensed attorney. Nobody can tell you how this ends. What we can do is read his sentence computation next to the statute and tell you, on paper, whether the date on that screen is the number it ought to be.
