Plan the Arrival Day Around Your Jet Lag
The arrival day isn't lost to jet lag by accident — it's lost by improvising. This takes your landing time and the size of the time shift, and plots the day: when to sleep, when to eat, when to get light, and when to push through to the local bedtime. Local only; nothing leaves the tab.

The workflow
Enter the times that actually matter
Departure, arrival, and the time difference — east or west, and how many hours. The size of the shift is what scales the plan; a two-hour shift is a different day than a nine-hour one.
Follow the light rule, not your eyelids
Light is the strongest lever on the body clock. The plan puts bright light at the local morning and dims it near local bedtime — even when your body says otherwise.
Nap only inside the window the plan gives you
A short nap early on is fine; a four-hour crash at 4pm is the week's jet lag. The plan marks the nap window, and 'no nap after it' is the rule that matters most.
Eat on the local clock from the first meal
Meals are the other clock-setter. Eating breakfast at local breakfast time — however little you want it — tells the body which day it's on.
Worked example
Sample: a westbound flight landing at 2:40pm, 9-hour shift Land 2:40pm local Nap window 3–4pm, 20 minutes max Light bright until 7pm, dim after Bedtime push to 10pm local Uploaded nothing — plotted in the tab

What breaks this
Guessing the time difference shifts the whole plan — enter the real shift. Taking the 'one long nap' instead of the window is the single mistake that decides the rest of the week; the window exists for a reason. Staying in the dark hotel room all afternoon is the other one — light is the lever, and the plan's whole job is to put it where it counts.
