A worked example
For an 8.30 AM arrival, 20 minutes of travel, and a 10-minute buffer, leave at 8.00 AM. Allow 30 minutes to get ready and start at 7.30 AM.
What the calculation assumes
The planner subtracts the minutes you enter from a local clock time. It does not estimate traffic, walking speed, school opening times, or public transit. Crossing midnight shows a previous-day label.
Set a realistic buffer
Include the walk from parking, handover, and any queue you usually encounter. Recheck the plan when the route or arrival time changes.

Keep this in your child’s bag list
