Nunzio Di Fabio conceived byourit and develops the content and interpretations of the biorhythm model used in the project.
People, calculation and interpretation
About us: people, method and limits
byourit is a project by Nunzio Di Fabio and Maximilian Giurastante. It offers calculations based on the classic three-cycle biorhythm model and personal or relationship readings.
Objective
Offer tools to explore the classic biorhythm model and compare its results with your own experience.
Methodology
From a birth date, we calculate the position of three conventional cycles: physical at 23 days, emotional at 28 and intellectual at 33. Comparing two people produces three scores and their simple average. Relationship type guides the interpretation text without changing the weights in the average.
A tool for personal exploration
Our Mission
Offer tools to explore the classic biorhythm model and compare its results with your own experience.
You can compare the model with your observations and discuss it with people you know, without relying on it for health, work or relationship decisions.
Method, history and scientific evidence
Our Method
From a birth date, we calculate the position of three conventional cycles: physical at 23 days, emotional at 28 and intellectual at 33. Comparing two people produces three scores and their simple average. Relationship type guides the interpretation text without changing the weights in the average.
People and editorial work
We distinguish Magazine articles from readings generated by the service. Articles identify their author or editorial team and dates. Readings combine calculations with the project’s interpretive content; the privacy policy describes data processing where artificial intelligence is involved.

History of the classic model
Key Authors in the History of Biorhythmology
These authors document a historical tradition. Their inclusion does not establish that the model works: our sources page separates historical hypotheses from experimental evidence.
Wilhelm Fliess
1858–1928
Physician and thinker, considered the modern rediscoverer of the 23 and 28-day cycles.
Hermann Swoboda
1873–1963
Developed a historical theory of psychological periodicity.
Alfred Judt
Contributed to the logical structuring of biorhythmic cycles.
Eugenio Soriani
1894–1981
Introduced original concepts on qualitative energy platforms and biorhythmic potential.
Livio J. Vinardi
1930 - 2009
Systematized the classic three-cycle model that inspires byourit.
Historical Evolution of Biorhythmology
The development of biorhythmology can be traced through six distinct historical periods
A historical classification within the biorhythm tradition, not a sequence of scientific validations.
Mythical Period
Spiritistic or Magnetic Period
Metaphysical Period
Scientific Period
Parapsychological Period
Contemporary Integration
The model and its limits
The model and its limits
From a birth date, we calculate the position of three conventional cycles: physical at 23 days, emotional at 28 and intellectual at 33. Comparing two people produces three scores and their simple average. Relationship type guides the interpretation text without changing the weights in the average.
The numbers are reproducible with the same inputs and method. This does not establish that the cycles measure energy, emotions, cognitive ability or relationship quality. The fixed-cycle theory is not supported by the empirical validation reviewed in our sources. Readings are prompts for reflection, not diagnoses, predictions or criteria for medical and professional decisions.
You can compare the model with your observations and discuss it with people you know, without relying on it for health, work or relationship decisions.
