Jesus was on the cross for approximately six hours. According to the Gospel accounts, Jesus was crucified around the third hour (9 a.m. Jewish time) and died around the ninth hour (3 p.m. Jewish time)

. This timeline is supported by Mark 15:25, which states Jesus was crucified at 9 a.m., and Matthew 27:45-46, which records darkness from noon to 3 p.m., the time of Jesus' death

. The difference in timekeeping systems between the Jewish day (starting at 6 a.m.) and the Roman day (starting at midnight) explains some variations in the Gospel narratives. John's Gospel uses Roman time, noting Jesus' trial before Pilate at about the sixth hour (6 a.m.), while the Synoptic Gospels use Jewish time for the crucifixion events

. In summary, Jesus was on the cross from about 9 a.m. until about 3 p.m., totaling roughly six hours of crucifixion before His death
