A Manhattan federal judge scolded lawyers for the accused Chelsea bomber, accusing them on Wednesday of dragging their feet and demanding they hurry up and get ready for trial — by the end of March.

“I can tell you, we’re working hard as we do on every case,” said Peggy Cross-Goldenberg, a lawyer for Ahmad Khan Rahimi.

“This is not every case,” a frustrated Judge Richard Berman shot back.

Rahimi stands accused of setting off pipe bombs in New York and New Jersey in September that injured dozens of people.

Berman has set a trial date for March 27 — four months after Rahimi’s November indictment.

Rahimi was arrested in September in a violent shootout that injured two New Jersey cops.

After the arrest, the feds found Rahimi carrying a handwritten journal lauding al Qaeda leaders like Osama bin Laden and Anwar al-Awlaki, they said.

Rahimi — whose name is also spelled Rahami — faces a mandatory life sentence if convicted.
