"EASTER" in Acts

 ...intending after Easter to bring him forth to the people.

Acts 12:4

"EASTER (AV Acts 12:4), An anachronistic mistranslation of the Gk. pascha (RSV, NEB, "Passover"), in which the AV followed such earlier versions as Tyndale and Coverdale. The Acts passage refers to the seven-day Passover festival (including the Feast of

Unleavened Bread). It is reasonably certain that the NT contains no reference to a yearly celebration of the resurrection of Christ." (International Standard Bible Encyclopaedia, edited by Geoffrey Bromiley, Vol 2 of 4, p.6, article: Easter)
"The term Easter was derived from the Anglo-Saxon 'Eostre,' the name of the goddess of spring. In her honor sacrifices were offered at the time of the vernal equinox. By the 8th cent. the term came to be applied to the anniversary of Christ's resurrection." (International Standard Bible Encyclopaedia, edited by Geoffrey Bromiley, Vol 2 of 4, p.6, article: Easter)
