Trip Duration Calculator

Break a trip into travel and destination time and check the ratio.

About Trip Duration Calculator

Long-haul travel and jet lag recovery can consume half of a short trip. The usable share is what determines whether the distance is worth it for the time available. Below about 40 per cent usable time, extending the trip by two days often adds more usable time than the two days themselves.

Formula

Trip Duration

Usable days = total days − travel days − jet lag recovery days

travel days
Total travel hours divided by 24
recovery days
Days at reduced capacity while adjusting to the new time zone

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
