Jesus' only sign of Messiahship was that He would be in the grave three days and three nights (72 hours), as stated in Matthew 12:38-40. This cannot fit between a Friday afternoon crucifixion and a Sunday morning resurrection, so the traditional timing invalidates the sign. The solution lies in recognizing that two Sabbaths fell in that week. Jesus was killed on Passover, a preparation day, and buried before sunset because sunset began a Sabbath (Mark 15:42; Luke 23:54; John 19:14). That Sabbath was not the weekly one but an annual high-day Sabbath, the first day of Unleavened Bread, as John 19:31 confirms. The weekly Sabbath followed it. In the year of the crucifixion, Passover fell on a Wednesday, and Jesus was entombed late Wednesday afternoon before the high-day Sabbath began. He lay in the grave from Wednesday night through Saturday, a full 72 hours, and was raised on the weekly Sabbath afternoon before sunset. This is the only timing that satisfies the sign of Jonah. The resurrection did not make the Sabbath holy, since God raised Him on a day already set apart. The resurrection therefore gives no basis for Sunday worship, which is a human tradition rather than a divine ordinance.

Jesus' sign of three days and three nights (72 hours) in the tomb rules out a Friday crucifixion and Sunday-morning resurrection. The Sabbath following the crucifixion was not the weekly Sabbath but an annual high-day Sabbath. John 19:14, 31 calls the crucifixion day "the preparation of the Passover" and says "that sabbath day was an high day." The annual holy days, all called Sabbaths in Leviticus 16 and 23, fall on varying weekdays. Jesus was crucified on the Passover, the 14th of Abib, which that year was Wednesday, and the 15th, the Feast of Unleavened Bread, was the annual Sabbath on Thursday. Joseph of Arimathea hurried to bury Jesus late Wednesday afternoon before that Sabbath began. The resurrection came at the same time of day, late Saturday afternoon, at the close of the weekly Sabbath. The decisive proof is the pairing of Mark 16:1 with Luke 23:56. The women bought spices after the Sabbath had passed, yet rested on the Sabbath according to the commandment. Only two Sabbaths with a day between, Thursday's annual Sabbath and Saturday's weekly Sabbath, with spice preparation on Friday, harmonizes the texts. Matthew 28:1 in the Greek uses the plural "Sabbaths," which most English versions obscure; Ferrar Fenton's version renders it correctly. Hence there were two separate Sabbaths that week.

Two Sabbaths fell during the week of the crucifixion: an annual holy-day Sabbath and the weekly seventh-day Sabbath. The claim that every Sabbath is the seventh day and that a preparation day must be Friday is false. In Exodus 12, God calls the Passover (Abib/Nisan 14) a feast but never a Sabbath, while the first and seventh days of Unleavened Bread (the 15th and 21st) are holy convocations. Both cannot fall on a Saturday, so annual Sabbaths fall on varying days of the week. Since Exodus 16 shows the day before a Sabbath is a preparation day, any Sabbath, annual or weekly, has its own preparation day. Jesus kept Passover on the correct day, which that year was Wednesday. He was crucified that day and hurriedly buried before sunset because "the Sabbath drew near" (Luke 23:54; John 19:42). Thursday, the 15th, was the first day of Unleavened Bread, the annual Sabbath, when the tomb was secured with a guard (Matthew 27:62-66). On Friday, after that holy day, the women prepared spices, then rested on the weekly Sabbath "according to the commandment" (Luke 23:55-56). This shows two preparation days that week, one for each Sabbath. Reading only one Sabbath compresses the timeline into a Friday crucifixion and Sunday resurrection. That timeline cannot yield the three days and three nights of the sign of Jonah (Matthew 12:40). Jesus rose as the weekly Sabbath ended, 72 hours after burial.

Two Sabbaths fell within the 72 hours between Christ's burial and resurrection: an annual high-day Sabbath and the weekly Sabbath. All four gospels say Jesus died on a preparation day, which is usually assumed to be Friday. But holy days can fall on any weekday, so the preparation day can too. Passover, Nisan 14, was itself the preparation for the first day of Unleavened Bread, and John 19:31 calls the following Sabbath "a high day." Mark 16:1 says the women bought spices "when the Sabbath was past," while Luke 23:56 says they prepared spices and then "rested on the Sabbath according to the commandment." Since Joseph barely finished the burial before sunset, the women could not have bought spices before the first Sabbath began. The sequence is therefore that they observed the holy day, bought and prepared spices on the day between, and then rested again on the weekly Sabbath. This yields a Wednesday crucifixion and burial at sunset, a high-day Sabbath on Thursday, spice preparation on Friday, and a resurrection at the end of the weekly Sabbath, exactly 72 hours later. Matthew 28:1 supports this, since the Greek reads "after the Sabbaths" in the plural, though translators have rendered it as singular. The two-Sabbath reading also accounts for the Emmaus disciples counting Sunday as the "third day" from Thursday's actions by the chief priests, and for the request to guard the tomb through the third day.

Crucifixion week contained two Sabbaths: an annual high-day Sabbath and the regular weekly Sabbath. Jesus was crucified on Wednesday, Nisan 14, the Passover, and died at the end of that day. Passover is not a holy day but always a preparation day for the first Day of Unleavened Bread, so a preparation day need not fall on Friday. Joseph of Arimathea placed the body in the tomb just before sunset, as the high-day Sabbath of Nisan 15 was about to begin (Luke 23:49-54). The women watched, then went home. Luke 23:56 says they prepared spices and fragrant oils, which as observant Jews they could not have done on the holy day. They must have done it after the high day, on Friday, when they bought and prepared the cloth and spices. Then they rested on the weekly Sabbath according to the commandment. Mark 16:1 confirms this, saying the Sabbath high holy day was past when they bought the spices. Because two preparation days fell in the week, one for the annual Sabbath and one for the weekly Sabbath, the Friday-to-Sunday tradition collapses. Counting three full days and nights, exactly 72 hours, from late Wednesday brings Jesus' resurrection to the end of the weekly Sabbath near sunset. The women found the tomb already empty early Sunday morning, about twelve hours after He had risen.

Jesus was crucified on a Wednesday, the Preparation Day before a Sabbath. That Sabbath was not the weekly Sabbath but the First Day of Unleavened Bread, a high day. Since the Passover, the day of the crucifixion, was also the Preparation Day for the First Day of Unleavened Bread, Joseph of Arimathea went to Pilate and asked for the body when evening came, as Mark 15:42-43 records. The burial was therefore completed just before that annual Sabbath began. The request by the chief priests and Pharisees to Pilate to seal and guard the tomb came on the next day, the day following the Day of Preparation, which was Thursday, the First Day of Unleavened Bread. The weekly Sabbath then followed, and the women came to the tomb as the first day of the week began to dawn, "after the Sabbath" (Matthew 28:1). The tomb was sealed and guarded the whole time, so that the empty tomb at the end of the three days and three nights was a work of God's miracle and not theft by the disciples.
