MEMORANDUM **

Clarence Walker appeals pro se from the district court’s judgment denying his 28 U.S.C. § 2241 habeas petition. We have jurisdiction under 28 U.S.C. § 2253, and we affirm.

*669 Walker contends that his 12-month period of home confinement should have been counted against his 40-month period of imprisonment. This argument lacks merit because the home confinement was imposed as a special condition of supervised release. See 18 U.S.C. § 3624(e) (“The term of supervised release commences on the day the person is released from imprisonment .... ”).

Walker also contends that the Bureau of Prisons (“BOP”) had a duty to contact the district court to resolve an ambiguity in the judgment. Because there was no ambiguity, the BOP had no such duty. See United States v. 60.22 Acres of Land, 638 F.2d 1176, 1178 (9th Cir. 1980).

AFFIRMED.
