Not only is it currently passover for Jews (Passover began on Wednesday evening, and it lasts 8 days.), but Christianity recognizes how closely Easter and Passover are linked. Not only was Jesus' last supper a Seder meal, but in many ways his death was a new Passover, that saved not only the first born son from death, but all of humanity. Most languages recognize this with their word for Easter (Pascha, Paques, Pasqua, Pascua, etc.)
