Here is everything you need to know before the blockbuster affair just nine days before Election Day.

The 45th president is scheduled to deliver remarks at 5 p.m.

The doors of the World’s Most Famous Arena will open to the public at 12 p.m.

The Trump campaign offered supporters the opportunity to register for tickets through its website on a first-come, first-served basis.

Registrants could only receive a maximum of two tickets per cell phone number used to secure admission.

There are usually long lines to get through security at Trump rallies, so it is recommended that attendees arrive early once the doors open.

The Post will also have a live blog of Trump’s rally running throughout the day.

New York City officials have not yet announced any road closures related to Sunday’s rally. However, attendees are strongly encouraged to take public transportation to MSG if at all possible.

Penn Station, which sits beneath the Garden, can be accessed via the 1, 2 and 3 subway lines. The B,D,F,N,Q and R trains stop at 34th Street and 6th Avenue, while the A,C, and E trains stop at 34th Street and 8th Avenue with underground access to the arena.

Penn Station is also a hub for the Long Island Railroad. Please check MTA.info for updated schedules or download the MTA TrainTime app to purchase tickets and stay up to date with the latest alerts.

The former president has long maintained that he believes he can win his home state — and has spoken about doing a rally at Madison Square Garden since March 2023, when he was indicted on business fraud charges.

The 78-year-old Republican nominee is expected to speak about his policies and how he would turn New York around as the 47th president.

“President Trump’s message to New York City is simple and built on his winning record: If you want to return to the strongest economy in over 60 years, rising wages, quality jobs, strong borders, and safer neighborhoods, then vote for the Trump-[JD] Vance ticket,” the campaign said in promoting the event.

A Trump adviser told The Post that the MSG appearance — while it likely won’t turn New York red — will create waves in national media and dominate headlines on an otherwise sleepy Sunday.

A Republican hasn’t carried New York since Ronald Reagan defeated Democrat Walter Mondale in 1984 and polling shows Vice President Kamala Harris leading Trump by double digits.

Perhaps most importantly, the appearance will serve as an opportunity for the campaign to fundraise and give a boost to down-ballot candidates, especially on tightly contested congressional races across New York.

Since it opened in February 1968, the current incarnation of MSG has hosted the Democratic National Convention three times — in 1976, 1980 and 1992 — and the Republican National Convention once, in 2004.

In the past, the Garden’s predecessor, about 15 blocks up Eighth Avenue, was a popular place for candidates to make their closing arguments to the country.
