   OPINION

PER CURIAM.

Appellant, Joseph Watkins, timely appeals from the District Court’s denial of his petition for a writ of habeas corpus.

Watkins, a federal inmate, filed a petition under 28 U.S.C. § 2241 challenging the administration of his sentence. Many of the issues therein had been raised previously in a 2002 petition and rejected both by the District Court and by this Court on appeal. See M.D.Pa. Civ. No. 02-cv-1903; C.A. No. 04-1097. At the time this earlier petition was filed, Watkins had a full term expiration date of January 24, 2008, and a projected release date, factoring in good time credit, of December 12, 2005. We agree with the District Court’s refusal to revisit petitioner’s old claims and to consider only those alleged miscalculations in petitioner’s sentence which occurred after the period addressed in his prior petition. The instant petition appears to allege a miscalculation of his good time credit during this period, which has led to a projected release date of November 13, 2007. The District Court found no error in the government’s calculations and rejected the petition.

We exercise jurisdiction pursuant to 28 U.S.C. §§ 1291 & 2253 and undertake pie-nary review of the judgment of the District Court. See Ruggiano v. Reish, 307 F.3d 121, 126 (3d Cir.2002). Like the District Court, we find no error in the government’s calculation of petitioner’s release date. When we last reviewed petitioner’s sentence, the full term expiration date was January 24, 2008. Factoring in good time credit, his projected release date was December 12, 2005. Since that time, Watkins has been penalized for various infractions by the forfeiture of 688 days of good time credit. He also earned an additional 7 days of good time credit for time spent in a Residential Reentry Center. Finally, the Bureau of Prisons corrected a computation error in his sentence which led to the addition of 27 days to his full term release date and the addition of 7 days projected good time credit. In total, these changes have resulted in the addition of 701 days to his projected release date. Petitioner does not challenge the validity of these adjustments, but rather contends “improper computation.” The government has made its calculations correctly and set Watkins’s projected release date as November 13, 2007, 701 days after December 12, 2005.

Accordingly, we will affirm the judgment of the district court. Petitioner’s motion for summary reversal is denied. 
      
      . As the events in this case are familiar to the parties and ably summarized in the District Court's memorandum, we limit ourselves to a short summary of the relevant changes in petitioner’s release date.
