## Description

A mobile app that calculates and plots the 3 biorhythm cycles (physical: 23 days, emotional: 28 days, intellectual: 33 days) based on a birth date, with a graph to visualize the curves over 7 days.<br><br>Calculation:<br><br>- Lived days: instead of &quot;age × 365 + days since birthday + leap days&quot;,<br><br>the code simply uses `(targetDate - birthDate).Days`. .NET natively supports the<br><br>Gregorian calendar (including leap days): the result is accurate and simpler<br><br>to maintain than manual counting, for a strictly identical result.<br><br>- Position in the cycle: `liveddays % cycleLength` (23, 28, or 33) — this is<br><br>exactly the &quot;remainder of the division&quot; described in the method.<br><br>- Displayed value (-100% to +100%)**: `sin(2π × position / cycle length) × 100`,<br><br>which gives the classic sine wave of the biorhythm (0 = critical day, +100 = peak, -100 = trough) rather than a simple day number.<br><br>- Critical day: detected by tolerance (`|value| &lt; 5%`) rather than by strict equality,<br><br>because 23 and 33 being odd, the exact crossing of zero never falls exactly on a whole day.
