Lincoln's Birthday is observed on February 12 and commemorates the birth of Abraham Lincoln, the 16th President of the USA, born in 1809. The earliest known observance of this holiday dates back to 1874 when a Buffalo, New York, druggist campaigned for its recognition. It is a legal holiday in states such as California, Arizona, Indiana, Missouri, New York, Connecticut, Illinois, and New Jersey. In some states, Lincoln's Birthday is combined with Washington's Birthday as part of President's Day, celebrated on the third Monday of February. Traditional ceremonies include wreath-laying at significant locations such as the Abraham Lincoln Birthplace National Historic Site in Hodgenville, Kentucky, and the Lincoln Memorial in Washington, D.C.
