Before You Reach Out

Most questions about our fasting calculator are answered in the FAQ section on the homepage. Before writing in, take a look there, it covers the most common questions about fasting protocols, calorie estimates, time-zone handling, and which foods break a fast.

What We Can Help With

  • Reporting calculator results that look wrong for your inputs
  • Reporting broken links, typos, or content errors
  • Suggesting new calculators or features
  • Partnership and content inquiries
  • Questions about our sources, formulas, or methodology

What We Can't Help With

We're not doctors, dietitians, or therapists. We can't give you personalized medical advice, diagnose conditions, or recommend fasting protocols based on your health history. If you have a medical condition, take medication, are pregnant or breastfeeding, or have a history of eating disorders, talk to a qualified healthcare provider before starting intermittent fasting.

Response Times

We read every email. Simple questions are usually answered within 1-2 business days. Bug reports and factual corrections are prioritized, if you've found an error in our content or a calculation that looks off, we typically respond within 24 hours. Feature requests take longer because we review them in monthly planning batches.

Privacy

Emails sent to contact@fastingtimecalculator.com are read only by our team. We don't share your email with third parties, add you to mailing lists, or use your message for marketing. See our privacy policy for details on how we handle your data.
