Zohran Mamdani will be sworn as New York City mayor on New Year 2026

Zohran Mamdani will become mayor of New York City as the clock ticks over into 2026 — but the celebrations are set to last through New Year’s Day.

The Democrat’s team is planning two separate swearing-in ceremonies Thursday — a small, private one with his family in an old subway station around midnight, followed by a large event in the afternoon that will include a public block party outside City Hall.

As a new mayor’s term begins immediately with the new year, it has been customary for the city’s incoming leaders to hold two events.



Outgoing mayor Eric Adams held his initial swearing-in at Times Square shortly after the famous ball drop, while Adams’ predecessor, Bill de Blasio, took his first oath at home in Brooklyn.

For his part, Mamdani will take his initial oath at the former City Hall subway station in Manhattan — one of the city’s original stops on its subterranean transit system, known for its tiled arches and vaulted ceilings.

New York Attorney General Letitia James, a political ally and notable foe of President Donald Trump, will administer the oath of office.
