Skip the Jet Lag Calculator

“Just enter your travel information and your normal sleep/wake times, and this calculator will show you how to adjust your resting schedule a little at a time as your departure date approaches. No more days wasted in brain fog and lethargy, only half-enjoying the meals you traveled around the globe to eat! It even lets you know if melatonin will or won't be helpful for a specific itinerary. It hasn't failed me yet, though I've only used it so far for San Francisco to Manila trips.”
