Driving Time Calculator

This works out how long a drive actually takes, not just the distance divided by the speed. Enter the road distance and the speed you hold while moving, then add a traffic allowance, how often you stop to rest and the range you get on a tank or a charge, and it returns the time behind the wheel, the stop time, the total journey and the local clock time you arrive. A second mode runs it backwards and gives the latest minute you can leave to make a deadline. Both ends take a UTC offset, so a drive that crosses a time zone lands on the right clock.

Calculator Type
Units
Road distance, not the straight line between the two places.
The speed you hold while actually moving. Stops and traffic are handled separately below, so do not shade this figure down for them.
Only used when the picker above is set to custom. It stretches the driving time by this percentage.
Two hours is the usual advice. Set it to 0 for no rest breaks.
In the same unit as the distance. Use the range you would actually drive before refuelling, not the brochure figure. Set it to 0 to leave fuel stops out.
Ten minutes for a pump, thirty or more for a rapid charger.
New York in winter is -5, Chicago -6, Denver -7, Los Angeles -8, London 0, Berlin 1.
Leave both offsets the same if the drive stays inside one zone.
Local clock time where you set off. Leave it empty to get the journey time on its own.
