A flight from New York (JFK) to Frankfurt (FRA) typically takes about 7 h 30 min. The return, Frankfurt to New York, takes about 8 h 45 min. The distance is 6,189 km (3,845 miles) along the great-circle path.
The jet stream, a fast river of air at cruising altitude, blows mostly from west to east. Flying New York to Frankfurt you ride it, about 7 h 30 min; flying Frankfurt to New York you fly into it, about 8 h 45 min. It is the same distance either way, which is why the westbound leg is usually the longer one.
Frankfurt is 6 hours ahead of New York (standard time; the gap shifts by an hour for part of the year when only one of them is on daylight saving). Leave New York at 10:00 and you land at about 23:30 Frankfurt time, the same day.
Frankfurt is 6 hours ahead, so your body clock has to move earlier. That is the harder direction: with no plan, expect about 6 days to feel properly adjusted.
For two or three days before, go to bed and get up an hour earlier each day, and get bright light soon after waking. Even a partial shift helps.
Set your watch to Frankfurt time as you board. On a typical morning departure you land around 23:30 Frankfurt time, in the evening or at night: try to sleep on the flight, with an eye mask and earplugs, drink water, go easy on alcohol, and go to bed soon after you arrive.
Get outdoor light in the morning and avoid bright light in the evening for the first few days. Keep any nap under 30 minutes, and have caffeine only before noon.

Distance is the great-circle distance between New York JFK and Frankfurt. Time is that distance at about 830 km/h cruise, adjusted for the prevailing jet stream, plus roughly 35 minutes for taxi, climb and descent.
