DEN-bound flights are the slower direction by about 65 minutes in our estimate: the route runs partly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

FRAEurope/Berlin — UTC+1 now; UTC+1 standard time, UTC+2 during daylight saving time
DifferenceFrankfurt is 7 hours ahead of Denver today.

Jet lag, flying DEN → FRA. Your body clock has to move 7 hours earlier, like an eastward trip. A common rule of thumb is that the body clock adjusts by roughly one time zone a day, so expect up to about 7 days to fully adjust. Shifting earlier (as here) is usually the harder direction; morning daylight at the destination helps. Flying the other way, the shift is reversed.
