Program for simple and quick determination of biorhythms. You will be able to compare your feelings on a particular day with the values of biorhythms, and note that this stuff really works.
Biorhythms - are periodic changes in the emotional, physical and intellectual condition of the person. Knowing your biorhythms, you can understand what to expect from your body in a given day.

The bottom graph shows the generalized value of all three biorhythms
Today widespread the classical model, which determines the length of cycles as the number of whole days - 23, 28 and 33. However, exists also improved model that accurately determines the period of cycles:
Physical -23.688437 days
Emotional - 28.426125 days
Intellectual - 33.163812 days
This program allows you to see the values of biorhythms, calculated by the classical model, and by the improved model.
If you do not complicate, write in comments to the program which model is most appropriate for your senses
