Set the 'from/dob' and 'to' dates to the desired dates. The 'from/dob' date is stored in the user settings and is remembered between visits (via the user settings cookie). The 'to' date defaults to today. To see a persons biorhythm set the from/dob date to their Date of Birth.
The Age is the number of years between the 2 dates.
The Annual Human Spirit is a type of Qi which travels to 12 areas of the body completing a cycle every 12 years (based on Sun Si-miao's interpretation). Needling and Moxibustion are prohibited in the area indicated. See Cheng-Tsai Liu (1999) for more detailed information.
The Sacrococcygeal Spirit (Kao Shen) works in a similar way but follows a different route around the body based on the 9 palaces and 8 trigrams. Needling and Moxibustion are prohibited in the area indicated. See Cheng-Tsai Liu (1999) for more detailed information.
The Jin Shin Jyutsu information is similar to the 2 previous items but the route and timings are slightly different.
For all of the above items, injury to the area during the selected age can cause serious injury to body's systems and in extreme cases even shorten life expectancy.
To get the current biorhythm of a person set the 'from/dob' date to the persons Date of Birth. The 'to' date should automatically default to today's date.
The Biorhythm chart displays the 3 primary biorhythm elements (Physical, Emotional, Intellectual) (plus 4 additional elements (Intuition, Aesthetic, Awareness, Spiritual) - as dashed lines ), as well as the moon phase (100% indicating Full Moon and 0% indicating a New Moon). I decided to include this in the app after reading Chapter 27 in Yang Li (1998) on the Book of Changes and biological clocks. The method mentions using the previous Winter Solstice as the Biorhythm from/start date (in Northern hemispheres this is 21/22 December, in Southern hemispheres it is 20/21 June).
