What is the significance of the term "Easter" to the Christian religion?
Most Christians refer to the week before Easter as Holy Week, which in Western Christianity contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus.
The modern English term Easter, cognate with modern Dutch ooster and German Östern, developed from an Old English word that usually appears in the form Ēastrun, -on, or -an; but also as Ēastru, -o; and Ēastre or Ēostre. Bede provides the only documentary source for the etymology of the word, in his eighth-century The Reckoning of Time. He wrote that Ēosturmōnaþ (Old English 'Month of Ēostre', translated in Bede's time as "Paschal month") was an English month, corresponding to April, which he says "was once called after a goddess of theirs named Ēostre, in whose honour feasts were celebrated in that month.
