Jehovah's Witnesses maintain a similar view, observing a yearly commemorative service of the Last Supper and the subsequent execution of Christ on the evening of Nisan 14 (as they calculate the dates derived from the lunar Hebrew calendar). It is commonly referred to by many Witnesses as simply "The Memorial". Jehovah's Witnesses believe that such verses as and constitute a commandment to remember the death of Christ though not the resurrection, and they do so on a yearly basis just as Passover is celebrated annually by the Jews.
