Estimate how many days it takes to recover from a time zone shift.
Researchers commonly estimate roughly half a day of adjustment per time zone crossed, with eastward travel adding a little more because it is harder to shift the body clock forward. The estimate gives a planning scale for the first few days. Understanding recovery length lets you schedule arrival activities conservatively and build in daytime sun exposure to resettle your body clock faster.

Recovery days = zones x 0.5 (eastward a bit longer)
