Question & Answer – How is the third hour of the day determined in Mark 15:25, Acts 2:15?

The Jewish people divided the twenty-four-hour day into two great divisions—the day, the light part, and the night, the dark part. The light part was subdivided into four sections; namely, the third hour, the sixth hour, the ninth hour, and the evening. The light part of the day began at six o’clock in the morning. The third hour of the day would be 9 a.m.
