I kept getting wrecked by jet lag flying around SE Asia and got tired of doing the math in my head every trip. So I built a calculator that actually tells you what to do.
Pick your origin and destination airports, choose when you're landing, and it gives you:
- Estimated recovery time (eastward travel is harder. the math is different)
- Whether you're traveling east or west and why it matters
- Personalized tips for light exposure, sleep timing, and meals based on your specific arrival time
