Intermittent Fasting Calculator

This is the clock arithmetic behind an intermittent fasting schedule and nothing more. Pick a protocol such as 16:8 or set your own fast length, say when you plan to eat first, and it returns the eating window with its open and close, the fasting window around it, the halfway point and evenly spaced meal times inside the window. A second tab runs it the other way, from the time you last ate to the moment the fast is up. It makes no claim about what fasting does and knows nothing about you, so whether a schedule suits you is a question for a doctor.
