Zohran Mamdani New York Mayor swearing-in ceremony date, time, locations. Details here

Zohran Mamdani, young upstart of the U.S. left, was readying Wednesday to take over as New York mayor for a term sure to see him cross swords with President Donald Trump. After the clocks strike midnight, bringing in 2026, Mamdani will take his oath of office at an abandoned subway stop, taking the helm of the United States' largest city. He will be New York's first Muslim mayor.

His office says the understated venue for the oath-taking reflects his commitment to working people, after the 34-year-old Democrat campaigned on promises to address the soaring cost of living.

But it remains to be seen if Mamdani -- virtually unknown a year ago -- can deliver on his ambitious agenda, which envisions rent freezes, universal childcare and free public buses.


Zohran Mamdani Swearing-In Ceremony


Mamdani's private swearing-in at midnight to start his four-year term will be performed by New York Attorney General Letitia James, who successfully prosecuted Trump for fraud.

A larger, ceremonial inauguration is scheduled for Thursday with speeches from left-wing allies Senator Bernie Sanders and Congresswoman Alexandria Ocasio-Cortez. The event is scheduled to begin at 1 pm (ET).

Around 4,000 ticketed guests are expected to attend the event outside City Hall.

Mamdani's team has also organized a block party that it says will enable tens of thousands of New Yorkers to watch the ceremony at streetside viewing areas along Broadway.

The new job comes with a change of address for Mamdani as he swaps his rent-controlled apartment in the borough of Queens for the luxurious mayor's residence in Manhattan.

Some had wondered if he would move to the official mansion given his campaigning on affordability issues. Mamdani said he is doing so mainly for security reasons.

Born in Uganda to a family of Indian origin, Mamdani moved to New York at age seven and enjoyed an elite upbringing with only a relatively brief stint in politics, becoming a member of the New York State Assembly before being elected mayor.
