Fasting Window Calculator
Track an intermittent fasting window with a timer.
Timing an eating window
Intermittent fasting structures eating into a window of the day with a fasting period around it, and keeping track of the hours is easier with a timer. This tracks your fasting and eating windows, so you can follow a schedule without watching the clock.
Set your fasting window and start the timer.
A pattern that suits some, not everyone
Intermittent fasting is one of several eating patterns some people find helpful, and it works for some as a simple structure. But it is genuinely not right for everyone: it can be unsuitable or unsafe for certain people — including those with particular health conditions, those on some medications, during pregnancy, and anyone with a history of disordered eating, for whom rigid eating rules can be harmful. Whether it is a good idea, and how to do it safely, depends entirely on the individual. This is general information, not medical or nutrition advice; before starting intermittent fasting, it is wise to speak with a doctor or registered dietitian, especially if you have any health condition. If your relationship with food feels difficult, please consider reaching out to a professional.
