Target
Required arrival time
7:30 PM
Backward time planner
Enter the time you must arrive or finish, then add preparation, travel, parking, and buffer time in the order they happen.
Arrive 7:30 PM − travel 40 − parking 10 − check-in 30 − buffer 15 = start 5:55 PM
Plan from the deadline
If you must arrive at 7:30 PM and need 40 minutes for travel, 10 for parking, 30 for check-in, and a 15-minute buffer, the plan needs 1 hour 35 minutes. Start at 5:55 PM.
Required arrival time
7:30 PM
40 + 10 + 30 + 15 minutes
1 hr 35 min
Target minus total duration

Build in breathing room
For a flight, appointment, or class, add traffic, queues, and unexpected delays as a separate step. If travel might take 30 to 50 minutes, turn on a duration range to see both the safer start and the latest possible start.
