General guidance, not medical advice. Everything is calculated in your browser; nothing you type is uploaded.
Offsets come from your browser’s time zone database for the travel date. Rule of thumb: about one day per zone eastward and two days per three zones westward.
Paris to New York in October is 6 time zones westward: about 4 days to adapt, going to bed one hour later on each of the two days before.
