Flight Delay Arrival Time Calculator
Add an entered delay to a scheduled arrival date and clock, including arrival on the next calendar date.
How to use Flight Delay Arrival Time Calculator
1. Enter Scheduled Arrival Time, Delay Duration. 2. Use a non-negative assumed delay. The same UTC offset is held throughout the addition; actual flight progress, recovery and schedule changes are not retrieved. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Add an entered delay to a scheduled arrival date and clock, including arrival on the next calendar date. Use a non-negative assumed delay. The same UTC offset is held throughout the addition; actual flight progress, recovery and schedule changes are not retrieved.
How the calculation works
Adjusted arrival clock = scheduled arrival clock + entered delay duration. Use a non-negative assumed delay. The same UTC offset is held throughout the addition; actual flight progress, recovery and schedule changes are not retrieved. Calendar and clock values are used as entered, independently of the browser time zone. This is a fixed-offset model: named-zone rules, daylight-saving changes, leap seconds and live flight information are not applied automatically. Use offsets valid at the dates concerned. Clock results round the final instant to the nearest second; calendar results stay within years 0100–9999.
Example
Worked example: Scheduled Arrival Time = "2026-10-12T23:30"; Delay Duration = "90 min". Result: 2026-10-13 01:00:00 (entered clock).
Practical tip
Use this for a simple stated-delay scenario, then compare the result with the airline’s latest arrival estimate.
Frequently asked questions
What does this result assume?
Use a non-negative assumed delay. The same UTC offset is held throughout the addition; actual flight progress, recovery and schedule changes are not retrieved.
Are current travel rules or locations checked?
Calendar and clock values are used as entered, independently of the browser time zone. This is a fixed-offset model: named-zone rules, daylight-saving changes, leap seconds and live flight information are not applied automatically. Use offsets valid at the dates concerned. Clock results round the final instant to the nearest second; calendar results stay within years 0100–9999.
How is the answer displayed?
Elapsed durations round to the nearest second, with nonzero subsecond values identified. Clock outputs show the full date and seconds on the entered or destination clock basis.
