Time Zone Arrival Day Calculator
Local arrival time is found by converting departure to UTC, adding travel and connection time, then applying the destination offset. The date can move forward or backward even when the clock time looks similar. This calculator reports a relative day offset; it does not model daylight-saving transitions, so use the offsets that apply on the actual travel date.
Planning estimate only. Check measurements and real-world constraints before buying materials or making a commitment.

Worked example
Use this example to check the calculator by hand before relying on a result.
Assumptions behind the result
- • Offsets are correct for the travel date.
- • Travel duration includes intended segments.
- • Decimal hours are entered consistently.
- • The result is a relative day, not a calendar date.
- • International date-line effects are captured through offsets.
Mistakes that change the answer
- • Adding the origin offset instead of subtracting it.
- • Ignoring daylight-saving differences.
- • Comparing local clock times without tracking the date.
