This project explores the concept of biorhythms, a pseudoscientific model that predicts cycles in an individual's life using mathematical calculations. The project involves creating a Python script that generates a graphical representation of these cycles, known as biorhythm graphs. The script utilizes libraries like NumPy and Matplotlib to process user-inputted dates and plot the three main cycles: emotional, physical, and intellectual. The resulting graph visually depicts the highs and lows predicted for the individual's life during the specified time period. While biorhythms lack scientific validity, they offer an intriguing exploration of cyclical patterns and provide a practical application of programming concepts.
