Simulator · The first three days, scheduled

Jet Lag Simulator

Pick your home city and the destination, the simulator computes the time shift and gives a light and sleep schedule for the days before and after the flight, with the hours to seek light, avoid it, and sleep, so the first morning on the trip is a real one.

The body clock shifts about an hour a day westward and a little less eastward, and light is the lever. This simulator takes the two time zones, decides which direction is shorter, and lays out a schedule: when to seek bright light, when to wear the sunglasses, when to sleep and when caffeine helps rather than hurts.

Simulators

One place, one month, one calendarJourney SimulatorChoose a place, a month, the days you have and how you travel. The simulator lays out a day-by-day timeline with temperatures, daylight, sleeping altitude, effort and cost, and flags the days where the model gets nervous. Open

What the month does to the placeClimate SimulatorHighs, lows and rain days for all twelve months of any place, with a feels-like line, a clothing verdict and a side-by-side comparison of up to three places for the month you can travel. Open
