What time should I leave?
Arrival time minus travel and buffer gives the time to leave; minus getting ready, the time to start. With a countdown.
Enter when you need to arrive, how long the trip takes, the time to get ready and a buffer for surprises: the page gives the time to start getting ready, the time to leave and the time left. A link starts the timer until departure.
Frequently asked questions
How is the departure time calculated?
The travel time and the buffer are taken off the arrival time, which gives the departure time; then the time to get ready is taken off to give when to start.
How much buffer should I plan?
A buffer of 10 to 15 minutes covers most surprises on a trip in town; plan more for a train, a flight or a rush-hour trip.
Can I be alerted when it is time to leave?
Yes: the “Start a timer until departure” link opens the timer set to the departure time; it rings when it is time to go.
