Sin and the grave.
noone knows for sure
During the three days in the grave, Jesus is believed to have descended into hell to proclaim victory over sin and death, and then rose from the dead on the third day.
While Jesus' body was in the grave, his spirit was in heaven. Luke 23:43 reads, "And [Jesus] said to [the criminal], "Truly I say to you, today you shall be with Me in Paradise." (NASB) The word "today" implies that Jesus was going to be in Paradise that very day, directly after his death.
