Nope! Every Jewish holiday is celebrated on two days, to prevent disagreement on which day they should be celebrated. Some Jews felt that you should start counting a day as in Genesis, where God works for a day, evening comes and morning follows, thus from morning to morning. Most followed the evening-to-evening definition now so much associated with Jewish observances. Thus, there were two observances of passover: on Thursday AND on Friday! This is fully in synch with the fact that Jesus celebrated Passover on Thursday night, but was the passover offering on Friday afternoon!
(I’ve read many Christians on this forum argue that either the death of Jesus was on a Thursday or the Resurrection was on a Monday.)
Maybe for Christians, but Jews have a different reason.
Two-day holidays are because of the original necessity to establish the new moon by witnesses to the Sanhedrin and then spreading the news by messenger.
