Question 1

Is biorhythm theory scientifically validated?

Accepted Answer

The math is real and precisely calculable — three sine-wave cycles derived from days elapsed since birth. The theory dates to the late 1800s (Wilhelm Fliess) and was popularized commercially in the 1970s. The claim that these cycles predict performance or mood has not been validated in controlled scientific studies.

Question 2

Will my reading change if I buy it again later?

Accepted Answer

Yes, deliberately — a biorhythm reading reflects the day it's generated, since your cycles keep moving. This is the one product on the site where that's true; a report from a different day will show a different position on the same underlying curve.

Question 3

What's included in the chart?

Accepted Answer

A real plotted 30-day chart — 7 days back, today, and 22 days ahead — for all three cycles, drawn from the actual calculated values, not an illustration.

Your cycles are already moving.
