Lincoln's Birthday is a legal holiday in some U.S. states, observed on the anniversary of Abraham Lincoln's birth on February 12, 1809. Arizona, California, Connecticut,Illinois,Indiana, Missouri, and New York observe the holiday. New Jersey formerly observed the holiday, but on September 29, 2008, the Senate and General Assembly of New Jersey enacted The Public Employee Pension and Benefits Reform Act of 2008 (Section 36 of P.L.1995, c.259 (C.52:14-17.31a)) eliminating Lincoln's Birthday as a public holiday for the purposes of conducting State government business, an act which also amended and supplemented various parts of retirement and other benefits for certain public employees.
In other states, a celebration of Lincoln's birthday is combined with a celebration of Washington's Birthday or as part of Presidents' Day. These celebrations occur on the same day as the Federal holiday, the third Monday of February, and not on Washington's or Lincoln's actual birthday.
