delivered the opinion of the Court.
A motion by a federal prisoner for postconviction relief under 28 U. S. C. § 2255 is subject to a one-year time limitation that generally runs from “the date on which the judgment of conviction becomes final.” §2255, ¶ 6(1). This case concerns the starting date for the one-year limitation. It presents a narrow but recurring question on which courts of appeals have divided: When a defendant in a federal prosecution takes an unsuccessful direct appeal from a judgment of conviction, but does not next petition for a writ of certiorari from this Court, does the judgment become “final” for post-conviction relief purposes (1) when the appellate court issues its mandate affirming the conviction, or, instead, (2) on the date, ordinarily 69 days later, when the time for filing a petition for certiorari expires?
In accord with this Court’s consistent understanding of finality in the context of collateral review, and the weight of lower court authority, we reject the issuance of the appellate *525 court mandate as the triggering date. For the purpose of starting the clock on §2255’s one-year limitation period, we hold, a judgment of conviction becomes final when the time expires for filing a petition for certiorari contesting the appellate court’s affirmation of the conviction.
I
In 1997, petitioner Erick Cornell Clay was convicted of arson and distribution of cocaine base in the United States District Court for the Northern District of Indiana. On November 23, 1998, the Court of Appeals for the Seventh Circuit affirmed his convictions. That court’s mandate issued on December 15, 1998. See Fed. Rules App. Proc. 40(a)(1) and 41(b) (when no petition for rehearing is filed, a court of appeals’- mandate issues 21 days after entry of judgment). Clay did not file a petition for a writ of certiorari. The time in which he could have petitioned for certiorari expired on February 22, 1999, 90 days after entry of the Court of Appeals’ judgment, see this Court’s Rule 13(1), and 69 days after the issuance of the appellate court’s mandate.
On February 22, 2000 — one year and 69 days after the Court of Appeals issued its mandate and exactly one year after the time for seeking certiorari expired — Clay filed a motion in the District Court, pursuant to 28 U. S. C. § 2255, to vacate, set aside, or correct his sentence. Congress has prescribed “[a] 1-year period of limitation” for such motions “run[ning] from the latest of” four specified dates. §2255, ¶ 6. Of the four dates, the only one relevant in this case, as in the generality of cases, is the first: “the date on which the judgment of conviction becomes final.” § 2255, ¶ 6(1).
Relying on
Gendron
v.
United States,
The Seventh Circuit affirmed. That court declined Clay’s “invitation to reconsider our holding in Gendron,” although it acknowledged that Gendron's “construction of section 2255 represents the minority view.”
The Fourth Circuit has agreed with Gendron’s interpretation of §2255. See
United States
v.
Torres,
*527 II
Finality is variously defined; like many legal terms, its precise meaning depends on context. Typically, a federal judgment becomes final for appellate review and claim preclusion purposes when the district court disassociates itself from the case, leaving nothing to be done at the court of first instance save execution of the judgment. See,
e. g., Quackenbush
v.
Allstate Ins. Co.,
Here, the relevant context is postconviction relief, a context in which finality has a long-recognized, clear meaning: Finality attaches when this Court affirms a conviction on the merits on direct review or denies a petition for a writ of certiorari, or when the time for filing a certiorari petition expires. See,
e. g., Caspari
v.
Bohlen,
Amicus
urges a different determinant, relying on verbal differences between § 2255 and a parallel statutory provision, 28 U. S. C. § 2244(d)(1), which governs petitions for federal habeas corpus by state prisoners. See DeBruin Brief 8-20. Sections 2255 and 2244(d)(1), as now formulated, were reshaped by the Antiterrorism and Effective Death Penalty Act of 1996. See §§ 101, 105, 110 Stat. 1217, 1220. Prior to that Act, no statute of limitations governed requests for federal habeas corpus or § 2255 habeas-like relief. See
Vasquez
v.
Hillery,
When “Congress includes particular language in one section of a statute but omits it in another section of the same Act,” we have recognized, “it is generally presumed that Congress acts intentionally and purposely in the disparate inclusion or exclusion.”

Wong Kim Bo,
Amicus would have a stronger argument if § 2255, ¶ 6(1), explicitly incorporated the first of § 2244(d)(1)(A)’s finality formulations but not the second, so that the § 2255 text read “becomes final by the conclusion of direct review.” Had § 2255 explicitly provided for the first of the two finality triggers set forth in § 2244(d)(1)(A), one might indeed question the soundness of interpreting § 2255 implicitly to incorporate § 2244(d)(1)(A)’s second trigger as well. As written, however, §2255 does not qualify “becomes final” at all. Using neither of the disjunctive phrases that follow the words “became final” in § 2244(d)(1)(A), §2255 simply leaves “becomes final” undefined.
Russello,
we think it plain, hardly warrants the decision
amicus
urges, one that would hold the § 2255 petitioner to
*530
a tighter time constraint than the petitioner governed by § 2244(d)(1)(A).
Russello
concerned the meaning of a provision in the Racketeer Influenced and Corrupt Organizations Act (RICO), 18 U. S. C. § 1961
et seq.,
that directed forfeiture to the United States of “any interest [a convicted defendant] has acquired ... in violation of [the Act].” § 1963(a)(1). The petitioner in
Russello
urged a narrow construction of the unqualified words “any interest . . . acquired.” Rejecting that argument, we observed that a succeeding subsection, § 1963(a)(2), reached “any interest in... any enterprise” the defendant conducted in violation of RICO’s proscriptions.' (Internal quotation marks omitted.) At that point, we referred to the maxim invoked by
amicus.
See
supra,
at 528. The qualifying words “in . . . any enterprise” narrowed § 1963(a)(2), but in no way affected § 1963(a)(1). The comparison of the two subsections, we said, “fortified” the broad construction we approved for the unmodified words “any interest . . . acquired.”
Russello,
Far from supporting the Seventh Circuit’s constricted reading of § 2255, ¶ 6(1), Russello’s reasoning tends in Clay’s favor. An unqualified term — here “becomes final” — Rus sello indicates, calls for a reading surely no less broad than a pinpointed one — here, § 2244(d)(1)(A)’s specification “became final by the conclusion of direct review or the expiration of the time for seeking such review.”
Moreover, as Clay and the Government urge, see Brief for Petitioner 22; Reply Brief for United States 7-8, one can readily comprehend why Congress might have found it appropriate to spell out the meaning of “final” in § 2244(d)(1)(A) but not in §2255. Section 2244(d)(1) governs petitions by state prisoners. In that context, a bare reference to “became final” might have suggested that finality assessments
*531
should be made by reference to state-law rules that may differ from the general federal rule and vary from State to State. Cf.
Artuz
v.
Bennett,
Amicus
also submits that 28 U. S. C. § 2263 “reinforces” the Seventh Circuit’s understanding of §2255. DeBruin Brief 20; accord,
Torres,
We do not find in § 2263 cause to alter our reading of § 2255. First,
amicus’
reliance on §2263 encounters essentially the same problem as does his reliance on § 2244(d)(1)(A): Section 2255, ¶ 6(1), refers to
neither
of the two events that § 2263(a) identifies as possible starting points for the limitation period — “affirmance of the conviction and sentence on direct review” and “the expiration of the time for seeking such review.” Thus, reasoning by negative implication from §2263
*532
does not justify the conclusion that §2255, ¶6(1)’8 limitation period begins to run at one of those times rather than the other. Cf. supra, at 529-531. Second, § 2263(a) ties the applicable limitation period to “affirmance of the conviction and sentence,” while §2255, ¶ 6(1), ties the limitation period to the date when “the judgment of conviction becomes final.” See
Torres,
* * *
We hold that, for federal criminal defendants who do not file a petition for certiorari with this Court on direct review, §2255’s one-year limitation period starts to run when the time for seeking such review expires. Under this rule, Clay’s § 2255 petition was timely filed. The judgment of the United States Court of Appeals for the Seventh Circuit is therefore reversed, and the ease is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
See
Derman
v.
United States,
Agreeing with the position advanced by the majority of the courts of appeals that have ruled on the question, the United States joins petitioner Clay in urging that Clay's §2255 motion was timely filed. We therefore invited David W. DeBruin to brief and argue this case, as amicus curiae, in support of the Seventh Circuit’s judgment. Mr. DeBruin’s able advocacy permits us to decide the case satisfied that the relevant issues have been fully aired.
The Courts of Appeals have uniformly interpreted “direct review” in § 2244(d)(1)(A) to encompass review of a state conviction by this Court. See
Derman
v.
United States,
Although recognizing that “the question is not presented in this case,” Tr. of Oral Arg. 27,
amicus
suggests that §2255’s limitation period starts to run upon issuance of the court of appeals’ mandate even in cases in which the defendant does petition for certiorari.
Id.,
at 27-28, 36-38, 41-42. As
amicus
also recognizes, however,
id.,
at 41, courts of appeals “have uniformly concluded that, if a prisoner petitions for certiorari, the contested conviction becomes final when the Supreme Court either denies the writ or issues a decision on the merits,”
