Shrove Tuesday (also known as Pancake Tuesday, Pancake Day, Mardi Gras, and Fat Tuesday) is the day preceding Ash Wednesday, the first day of Lent. Shrove Tuesday is observed mainly in English speaking countries,^{[citation needed]}, but is also observed in the Philippines and Germany. Shrove Tuesday is linked to Easter, so its date changes on an annual basis.

In most traditions the day is known for the eating of pancakes before the start of Lent. Pancakes are eaten as they are made out of the main foods available, sugar, fat, flour and eggs, the consumption of which was traditionally restricted during the ritual fasting associated with Lent.

Lincoln's Birthday is a legal holiday in some U.S. states including California, Connecticut, Illinois, Missouri, New Jersey, New York, and Indiana. It is observed on the anniversary of Abraham Lincoln's birth on February 12, 1809.

The earliest known observance of Lincoln's birthday occurred in Buffalo, New York, in 1874. Julius Francis (d. 1881), 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.^[1]
