TIME
Time difference & arrival
Choose cities to compare their local times at the same instant.
What time is it at your destination?
Uses your device clock and IANA time zones, including daylight saving on that date.
Is a time difference the same as flight duration?
No. A time difference compares local clocks at the same instant; flight duration is elapsed travel time. The displayed offset can change with date and daylight saving time.
Scope: Site calculations using the selected date and city time zones; not a guarantee of a flight schedule or changes.

Can the time difference change on my travel date?
Both UTC offsets are compared at the same instant. Daylight saving can change the difference, so choose a date and time when planning a future trip.
What happens when daylight saving skips or repeats a local time?
A skipped daylight saving time is rejected. For a repeated time, choose its UTC offset. Current time depends on your device clock and browser time-zone data. Use an up-to-date browser.

Can the arrival date be earlier than the departure date?
Yes. Local calendar dates may differ while the arrival instant still follows departure. Keep local dates separate from elapsed time.
