intellectual biorhythm
The intellectual cycle is the longest of the three biorhythm cycles, with a 33-day period. It was the last one proposed, in the 1920s, and in the theory (without scientific support) it would represent logical reasoning, memory and mental clarity.

The longest of the three cycles.
It is a popular theory, not a real biological measurement, that claims three aspects of life (body, emotions and mind) follow fixed sine-wave cycles, starting at birth and never changing period. This calculator reproduces the classic formula purely for curiosity and entertainment.
According to the theory, it would measure logical reasoning, memory and mental clarity, in a 33-day cycle from birth. It is the newest of the three cycles and, like the others, is symbolic interpretation with no scientific proof.
Austrian engineering professor Alfred Teltscher, in the 1920s, after informally noticing a pattern in his students' performance. The other two cycles (physical and emotional) come from Wilhelm Fliess and Hermann Swoboda, decades earlier.
It is not recommended. There is no controlled evidence that the cycle relates to real cognitive performance. Use it as curiosity, prepare for tests with study and rest, not with the biorhythm calendar.
By default we show today, but you can pick any other date, past or future, to see how the three cycles would look on that day.
