TL;DR
Google Maps calculates exactly when you need to leave to arrive on time – including real-time traffic.
How to do it
- Open Google Maps and enter your destination.
- Tap Directions.
- Tap the departure time shown at the top.
- Switch to "Arrive by".
- Enter your desired arrival time (e.g. 9:00 AM).
- Maps automatically calculates: "Leave by 8:23 AM" – based on current traffic.
Works for public transport too
For buses and trains, Maps shows the recommended connection so you catch the right departure.
Why this helps
- Google Maps uses real-time traffic data and historical patterns for its calculations.
- The departure time adjusts automatically when traffic conditions change.
- Perfect for meetings, flights, appointments – no more stress about "When do I need to leave?".
Tip
For long trips: check the night before. Construction and traffic jams can significantly increase travel time.
