Glossary
ETA
ETA stands for Estimated Time of Arrival.
Average speed
The average speed for the whole trip. Traffic, waiting time, and route conditions need separate judgment.
IANA time zone
A region-based time-zone identifier such as Asia/Tokyo or America/New_York.
knot (kn)
A speed unit used in marine and aviation contexts. 1 kn = 1.852 km/h.
Formulas
Driving time = distance / average speed
ETA = departure time + driving time + break time
Recurring break count = floor((driving time in ms - 1) / break interval in ms)
Notes
- This is an estimate. Actual arrival time can change because of traffic, weather, congestion, customs, loading, unloading, or other delays.
- At DST boundaries, the entered departure local time may not exist or may occur twice.
- Legal driving and rest rules differ by region, so this tool is not a substitute for operational or legal judgment.
FAQ
Does it include traffic or weather?
No. Add any safety margin or expected delay into the break time if you need a more conservative ETA.
Can I use different time zones?
Yes. You can set different IANA time zones for departure and arrival.
Does it support miles, mph, nautical miles, and knots?
Yes. The tool supports mi / mph as well as nm / kn.
How are recurring breaks calculated?
Enter how many minutes of driving happen before each break and how long each break lasts. The tool adds only the breaks that happen before arrival.
What does the share URL store?
It stores the departure date-time, time zones, distance, speed, break settings, and display settings. Do not include personal or sensitive information.
