When reading palms and trying to judge time on the lines of the palms, we can use the "system of seven".  Nature seems to use the system of seven. From the medical and scientific standpoint the number seven is the most important point of calculation. Our entire system undergoes a complete change every seven years. There are seven stages prior to birth, and the brain takes seven forms before it takes on the unique one of a kind character of your human brain. We have also discovered that the number seven has played a very important part in history. There are seven human races, seven wonders of the world, seven days in the week, seven colors, seven minerals, the three parts of our body each contain seven sections. The most important point that is important to us in judging time on the lines of our palms is that our entire system undergoes a complete change every seven years.

By using the seven year cycle on the lines of the hand, you can divide them into sections giving dates as accurately as possible.

When judging the time on the Life Line, Fate Line and other vertical lines, we will use the base of the second phalanx of the thumb and draw an imaginary line across the palm which is about the center of the hand. All measurements of time in terms of years can only be approximate so we do not know the time of death. When judging the time of the lines, in all instances they are spaced wider at the beginning of the lines, narrower toward the end of the lines.

The vertical lines, Fate, Sun, Health are real from the wrist upwards. The Life Line begins under the index finger circling the Mount of the Lower Mars and Mount of Venus. The line ends in  most cases under the Mount of Venus.

The Hart Line is read from the outer or percussion edge of the palm running horizontally across the palm toward the index finger.

The Head Line will most often start at the beginning of the Life Line and run horizontally across the palm toward the outer edge of the palm or percussion edge.
