💡 Why use this calculator?

Crossing time zones disrupts your internal clock, causing fatigue, poor sleep, and brain fog. Generic advice like "drink water" doesn't work—you need a plan tailored to your specific flight.

🔬 What you'll get:

  • Day-by-day schedule: Exact times for sleep, light exposure, and meals
  • Research-backed: Based on circadian rhythm science (not guesswork)
  • Personalized: Adapts to your timezone difference and travel direction
  • Realistic expectations: Know when you'll feel worst and when you'll recover
