Labor Day is Monday, Sept. 1, marking the unofficial end of summer for many New Yorkers.

The holiday brings a day off for most office workers and students, plus one last chance to enjoy beaches, barbecues and parades before fall begins.

It also means some city services will be unavailable and schedules will change. Here’s what to know.

Public transit

Subways and buses will run on a Sunday schedule on Labor Day, with some planned subway service changes in effect throughout the long weekend, the MTA says.

The transit agency is advising riders planning to travel by bus on Labor Day to check Sunday schedules and routes.

The Long Island Rail Road, meanwhile, will operate on a weekend/holiday schedule on Labor Day, and Montauk Branch trains will run on a Sunday schedule, according to the MTA.

“The 11.36 a.m., 1.46 p.m., and 4:17 p.m. trains from Montauk to Penn Station, the 6:21 p.m. train from Montauk to Penn Station and the 3:25 p.m. train from Southampton to Jamaica, usually scheduled to run Sundays, will instead run on Monday along with other added service from the Hamptons and Montauk,” the MTA noted. “This is in addition to regular Montauk Branch service.”

Metro-North Railroad riders will also see a number of service changes on the East and West of Hudson Lines over the long weekend.

Riders can check the MTA’s website, app or service changes map for transit updates.

Alternate side parking

Alternate side parking rules will be suspended for the holiday.

Sanitation

The city will not be collecting trash, curbside compost or recycling on Labor Day.

The Department of Sanitation is advising New Yorkers who normally receive Monday collection to put materials at the curb Monday evening for collection on Tuesday, September 2.

Beaches

All of New York City’s beaches will be open for Labor Day and will remain open through the final day of the summer season on Sept. 7.

Lifeguards are on duty from 10 a.m. to 6 p.m. during beach season.

Government offices

Since Labor Day is a federal holiday, all nonessential government offices, including the Department of Motor Vehicles, will be closed.  

Schools and libraries

All of the city’s public library branches will be closed from Saturday, Aug. 30 through Monday, Sept. 1.

Public schools will not be open, as the first day of school this year is Thursday, Sept. 4.

Post offices

Post offices will be closed on Labor Day, according to the U.S. Postal Service’s website.

Banks and financial markets

Most bank branches will be closed for the holiday. New York Stock Exchange markets will also be closed.

Retail and grocery stores

Most major retail stores, supermarkets and pharmacies will remain open, though hours may vary. Shoppers should check with individual stores for specific holiday hours.
