The notoriously tardy Mayor de Blasio stayed true to form Sunday night when he showed up late for a Hanukkah menorah lighting in Brooklyn.

De Blasio — who was booed at last week’s Christmas-tree lighting in Rockefeller Plaza — made the annual event at Grand Army Plaza a last-minute addition to his public schedule at 4:06 p.m., with City Hall setting his arrival time at 5:30 p.m.

But Hizzoner didn’t get there until 5:40 p.m., immediately hopping into the basket of a crane that lifted him and Rabbi Shimon Hecht of Congregation B’nai Jacob of Park Slope so they could light the 32-foot-tall menorah.

“He’s late to everything,” griped Mitch Cohen, 63, who traveled from Bay Ridge to celebrate the first night of Hanukkah. “He doesn’t even consider the people that he keeps waiting.”

De Blasio has repeatedly angered New Yorkers by showing up late to public events, most notably when he missed the 2014 tolling of a bell to commemorate the 265 people killed in the 2001 crash of American Airlines Flight 587 in the Rockaways.

When asked for comment, de Blasio’s office claimed he wasn’t late, though he was observed by the Post arriving 10 minutes after the scheduled lighting time.
