Most of this thread consists of people correcting you in this regard.
For instance, you criticized the Book of Mormon for being inconsistent with the Gospels about how long "darkness covered the land" when Jesus died. However, the Bible is itself inconsistent in similar ways: for instance, the Gospel chronology has Jesus in the tomb for one day and two nights, but he had promised to be in the "belly of the Earth" for three days and three nights.
According to how the Hebrews counted days, CHRIST was in the tomb 3 days. CHRIST had to be in the tomb before evening. The next day began at sundown, Friday. CHRIST was already dead an in Abraham's Bosom before that time.
Another possibility is as follows:
The problem with the commonly accepted belief regarding the crucifixion and resurrection is that there are not three days and three nights between Friday afternoon and Sunday morning. We believe the weight of scriptural and historical evidence leads to the conclusion that Jesus died on Wednesday afternoon, was hurriedly placed in the tomb of Joseph of Arimathea shortly before sunset that same afternoon (the eve of an annual Sabbath, the first day of Unleavened Bread; John 19:30-31, 42; Mark 15:42-46) and was resurrected by the Father shortly before sunset on Saturday, three days and three nights after being placed in the tomb, exactly as He had said.
This explanation is consistent with the details found in Scripture. It does not require a strained fitting of three days and three nights between Friday evening and Sunday by speculating about parts of days and nights. It reconciles the accounts of the women and the spices, found in Mark 16:1 and Luke 23:56. In the first account, the faithful women obediently rested during holy time and afterward procured the spices. In the second account, the women prepared the spices and afterward rested during holy time.
These accounts are reconciled by understanding that there were two periods of holy time during the week in question. Jesus was crucified on the Passover (Matthew 26:18-20; 1 Corinthians 5:7), which was the preparation day (Mark 15:42) for the first annual Holy Day on the Jewish calendar, the first day of Unleavened Bread. The women waited until this day was over, then bought and prepared the spices, then rested again on God's weekly Sabbath day, and then proceeded to the tomb to apply the spices to Jesus' body early on Sunday morning.
They visited the tomb after the holy Sabbaths (plural) of that week (as the original Greek of Matthew 28:1 should be translated). The annual Sabbath (annual Holy Days also are called "Sabbaths" [Leviticus 16:31; 23:24]) was Thursday, and the weekly Sabbath was Saturday. When they arrived at the tomb early Sunday morning, they found it empty and heard the announcement from the angel that Jesus was alive and was not there (Mark 16:6).
A significant amount of historical and scriptural evidence points to A.D. 31 as the year of Christ's crucifixion and resurrection. Among these indicators of an A.D. 31 crucifixion are the fulfillment of Daniel's prophecy of the coming of the Messiah (Daniel 9:24-26; Ezra 7 [Artaxerxes' decree]), and a careful consideration of three milestones: the likely date of Jesus' birth, His age when He began His ministry and the duration of His ministry.
The calculated calendar of the Jews places the Passover in A.D. 31 on Wednesday, and Jesus Christ's death on that day fulfilled His role as the true Passover Lamb of God (1 Corinthians 5:7). The next day, Thursday, was a holy (annual) Sabbath. On that Thursday, the chief priests and Pharisees went to Pilate to secure permission to seal and guard Jesus' tomb (Matthew 27:62-66). Later, on Sunday, the resurrected Jesus walked along the road to Emmaus and talked with two of His disciples, who discussed all the things that had happened, including the Thursday visit by the leaders to Pilate (Luke 24:13-14, 20). They mentioned that this day, Sunday, was the third day since all these things had happened (verse 21).
In summary, we believe that Jesus Christ, the Lamb of God, died for our sins on the Passover, was entombed for three days and three nights (72 hours) and then was resurrected and, after a period of further contact with the disciples, ascended to heaven to sit at the Father's right hand, far above all others in power, glory and honor (Ephesians 1:19-23).
