The earliest known observance of Lincoln’s birthday occurred in Buffalo, New York,
in 1874. Julius Francis, a Buffalo druggist, made it his life’s mission to honor the
slain president. He repeatedly petitioned Congress to establish Lincoln’s birthday
as a legal holiday.

The celebration of Groundhog Day had its origins from ancient European weather
lore. The early American reference to the custom can be found in a diary entry,
dated February 4, 1841, made by a Berks County, Pennsylvania storekeeper
James Morris. It was celebrated for the first time at Gobbler’s Knob in  the
city of Punxsutawney, Pennsylvania. Traditionally, if a groundhog comes out 
of his hole and sees its shadow, that means there will be six more weeks of
winter weather, no shadow means an early spring.

Civil Rights Movement. He was assassinated on Thursday, April 4, 1968 in Memphis,

a federal holiday to honor King. Martin Luther King, Jr. Day was observed for the
time on Monday, January 20, 1986. On January 17, 2000, the federal holiday
was officially observed in all fifty states for the first time.
