Cesar Chavez Day is an official state holiday in the U.S. states of California, Colorado and Texas. The day is commemorated to promote service to the community in honor of Cesar Chavez's life and work. Many, but not all, state government offices, community colleges, and libraries are closed. Many public schools in the state are also closed. Texas also recognizes the day, and it is an optional holiday in Arizona and Colorado. Although it is not a federal holiday, the President proclaims March 31 as Cesar Chavez Day in the United States, with Americans being urged to "observe this day with appropriate service, community, and educational programs to honor Cesar Chavez's enduring legacy."^[1] In addition, there are celebrations in his honor in Arizona, Michigan, Nebraska, and New Mexico and has been observed in California since 1995, in Texas since 2000 and in Colorado since 2003 as state holidays (optional in Texas and Colorado).^[2]

As a senator, Barack Obama made a call in 2008 for a national holiday in Chavez's honor, saying: "Chavez left a legacy as an educator, environmentalist, and a civil rights leader. And his cause lives on. As farm workers and laborers across America continue to struggle for fair treatment and fair wages, we find strength in what Cesar Chavez accomplished so many years ago. And we should honor him for what he's taught us about making America a stronger, more just, and more prosperous nation. That's why I support the call to make Cesar Chavez's birthday a national holiday. It's time to recognize the contributions of this American icon to the ongoing efforts to perfect our union." (Senator Barack Obama March 31, 2008)^[3] Grassroots organizations continue to advocate to create a national holiday. March 30, 2011, President Obama reiterated his support for the cause: "Cesar Chavez's legacy provides lessons from which all Americans can learn." ^[4]

Easter (Old English: Ēostre) or Pascha (Greek: Πάσχα, Paskha; Aramaic: פֶּסחא‎ Pasḥa; from Hebrew: פֶּסַח‎ Pesaḥ)^[1] is a Christian feast and holiday celebrating the resurrection of Jesus Christ on the third day after his crucifixion at Calvary as described in the New Testament.^[2][3] Easter is preceded by Lent, a forty-day period of fasting, prayer, and penance. The last week of Lent is called Holy Week, and it contains the days of the Easter Triduum, including Maundy Thursday, commemorating Maundy and the Last Supper,^[4][5] as well as Good Friday, commemorating the crucifixion and death of Jesus.^[6] Easter is followed by a fifty-day period called Eastertide or the Easter Season, ending with Pentecost Sunday. The festival is referred to in English by a variety of different names including Easter Day, Easter Sunday,^[7]Resurrection Day and Resurrection Sunday.

Easter is a moveable feast, meaning it is not fixed in relation to the civil calendar. The First Council of Nicaea (325) established the date of Easter as the first Sunday after the full moon (the Paschal Full Moon) following the northern hemisphere's vernal equinox.^[8] Ecclesiastically, the equinox is reckoned to be on 21 March (even though the equinox occurs, astronomically speaking, on 20 March in most years), and the "Full Moon" is not necessarily the astronomically correct date. The date of Easter therefore varies between 22 March and 25 April. Eastern Christianity bases its calculations on the Julian calendar whose 21 March corresponds, during the 21st century, to 3 April in the Gregorian calendar, in which the celebration of Easter therefore varies between 4 April and 8 May.
