What's Open/Closed on Martin Luther King, Jr. Day?

Monday marks the nation's observance of Martin Luther King, Jr's birthday.

King’s actual birthday is Tuesday, Jan. 15 — he would have been 84 this year — but the official holiday is always celebrated on the third Monday of January. This year, that falls on Jan. 21.

The day is marked as a federal holiday. All federal employees and offices are closed. Banks are closed, as well as the stock market. All New York State Department of Motor Vehicle offices are closed.

It is also a postal holiday, which means there is no regular mail delivery/pickup or retail services on Jan. 21.

Hempstead Town Hall and senior centers are also closed in observance of the holiday. The Homeowner Disposal Area in Merrick will be closed. Nassau County buildings and offices will be closed as well.

The Long Island Rail Road will operate on a Holiday Schedule. There will be 37 extra eastbound and westbound trains, to and from Penn Station, added on various branches to accommodate holiday travelers. Off-peak fares will also be in effect all day.

Sanitary District 1 services are on normal schedule.

The Hewlett-Woodmere Public Library is closed, while Peninsula Public Library will be open from 1 to 5 p.m.
