Biorhythm theory proposes that three biological cycles influence our daily life from birth: a 23-day physical cycle (strength, coordination), a 28-day emotional cycle (creativity, mood), and a 33-day intellectual cycle (concentration, analysis).

How do I calculate my biorhythm?

Enter your birth date in our calculator. It calculates the number of days since your birth and applies sine wave formulas for each cycle (23, 28, and 33 days). The chart shows your current position and 30-day forecast.

What are critical days in biorhythm?

Critical days occur when a cycle crosses the zero line, transitioning between positive and negative phases. During critical days, that aspect of your life may be unstable. Physical critical days suggest caution with exercise, emotional ones affect mood stability.

What is Biorhythm?

Biorhythm theory proposes that our lives are influenced by biological cycles that begin at birth. Three sinusoidal cycles affect our physical performance (23 days), emotional balance (28 days) and intellectual acuity (33 days).

The Three Cycles

Physical

Coordination, strength, well-being. When high, you have more energy for physical activity and endurance.

sin(2pi x t / 23) — 23-day cycle

Emotional

Creativity, sensitivity, mood. When high, your intuition and empathy are stronger.

sin(2pi x t / 28) — 28-day cycle

Intellectual

Concentration, memory, analysis. When high, your logical thinking and learning ability increase.

sin(2pi x t / 33) — 33-day cycle
