It honors the willingness of Abraham (Ibrahim) to sacrifice his young first - born son Ishmael (Ismail) as an act of submission to God's command, before God then intervened to provide Abraham with a lamb to sacrifice instead . In the lunar - based Islamic calendar, Eid al - Adha falls on the 10th day of Dhu al - Hijjah and lasts for four days . In the international Gregorian calendar, the dates vary from year to year, drifting approximately 11 days earlier each year . </Td> </Tr> <P> In addition to the federal / national holidays, many religious, ethnic, and other traditional holidays populate the calendar, as well as observances proclaimed by officials and lighter celebrations . These are rarely observed by businesses as holidays (Except for Easter and most often also on Good Friday); indeed, many are viewed as opportunities for commercial promotion . Because of this commercialization, some critics apply the deprecatory term Hallmark holiday to such days, after the Hallmark greeting card company . </P> <Table> <Tr> <Th> Date </Th> <Th> Name </Th> <Th> Remarks </Th> </Tr> <Tr> <Td> February 2 </Td> <Td> Groundhog Day </Td> <Td> The day on which folklore states that whether or not a local groundhog casts a shadow determines if the spring season will arrive early or on time . </Td> </Tr> <Tr> <Td> one day first week of February </Td> <Td> National Girls and Women in Sports Day </Td> <Td> A day of observance recognizing women's contributions to sports and society . </Td> </Tr> <Tr> <Td> March 8 </Td> <Td> International Women's Day </Td> <Td> A day set aside to honor women and their accomplishments in history . </Td> </Tr> <Tr> <Td> April 1 </Td> <Td> April Fools' Day </Td> <Td> A day that people commonly play tricks or jokes on family, friends, and co-workers, especially in English - speaking nations .

The holiday is often celebrated with parades and protests for workers' rights and other broad social issues . </Td> </Tr> <Tr> <Td> May 5 </Td> <Td> Cinco de Mayo </Td> <Td> Primarily a celebration of Mexican culture by Mexican - Americans living in the United States . Although this is the anniversary of the victory of the Mexican Army over the French at the Battle of Puebla in 1862, Cinco de Mayo is far more important in the USA than in Mexico itself, often celebrated even by non-Mexican - Americans .

"Black Friday" is not a holiday under that name, but California and some other states observe "The Day After Thanksgiving" as a holiday for state government employees . Virtually all schools, colleges, and universities are also closed, along with many non-retail private sector businesses . Federal government offices, post offices and federally chartered banks must open on Black Friday (unless the President issues an executive order or proclamation allowing them to close). It is called "Black Friday" because it begins the sales period when most American retailers make their profits for the year . Contrary to popular belief, Black Friday is not the busiest sales day of the year (that honor belongs to Christmas Eve, December 24). Rather, it is the barometer by which retailers are able to gauge December sales and whether they will indeed end the year "in the black" (instead of "in the red"). A busy Black Friday almost invariably indicates a busy shopping season, while poor sales on Black Friday usually herald a very slow season . </Td> </Tr> <Tr> <Td> December 7 </Td> <Td> Pearl Harbor Remembrance Day </Td> <Td> Day to mourn the attack on Pearl Harbor by the Japanese on December 7, 1941 . </Td> </Tr> <Tr> <Td> December 31 </Td> <Td> New Year's Eve </Td> <Td> Final Day of the Gregorian year .
