However, Easter falls on a different date each year. Easter Sunday and related celebrations, such as Ash Wednesday and Palm Sunday, are considered “moveable feasts,” although, in western Christianity, which follows the Gregorian calendar, Easter always falls on a Sunday between March 22nd and April 25th. In Eastern Orthodox Christianity, which adheres to the Julian calendar, Easter falls on a Sunday between April 4th and May 8th each year. In some denominations of Protestant Christianity, Easter Sunday marks the beginning of Eastertide, or the Easter Season. Easter. The last week of Lent is called Holy Week, and it contains the days of the Easter Triduum, including Maundy Thursday (also known as Holy Thursday), commemorating the Last Supper and its preceding foot washing,[8][9] as well as Good Friday, commemorating the crucifixion and death of Jesus.[10] Easter is followed by a fifty-day period called Eastertide, or the Easter Season, ending with Pentecost 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 March equinox.[11] Ecclesiastically, the equinox is reckoned to be on 21 March (although the astronomical equinox occurs on 20 March in most years), and the "Full Moon" is not necessarily on the astronomically correct date. The date of Easter therefore varies from 22 March to 25 April inclusive.
