health.circadian-phase-shift Calculator
Calculates how many days of light exposure adjustment are needed to shift the circadian phase by a given number of hours, for jet lag or shift work adaptation. Eastward travel requires circadian phase advance (~1 hour per day); westward requires delay (~1.5 hours per day) — different difficulty levels.
Inputs
Sleep Time Current Hr
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Sleep Time Target Hr
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Wake Time Hr
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Light Therapy Min
Reference formula or conversion factor shown for context.
Results
estimated days to shift
The value at the specified point or condition.
phase shift needed
The current phase of the cycle or process.
daily phase advance
The current phase of the cycle or process.
