Find the Arrival Calendar Date From Explicit Flight Clock Offsets
A late departure can arrive two calendar labels later without taking two full days. Use an offset-stamped departure, elapsed minutes and an explicit destination offset to check the date you need for a pickup or first accommodation night.

FIRST-LOAD
HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.
Data note: The arrival-date docket processes leg label | departure YYYY-MM-DDTHH:MM±HH:MM | elapsed minutes locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.
Perspective: Before: local clock labels obscured the destination date. After: an explicit instant conversion exposes date rollover without inventing a time-zone lookup.

Clock arithmetic only, not a verified itinerary, immigration check, jet-lag recommendation or arrival guarantee. Offsets are supplied by you and are not checked against a time-zone database. Confirm carrier times and destination clock rules with the carrier or travel provider before booking pickups or accommodation; allow separately for disruption and entry processing.

What $4 one-time adds
- unlimited subsequent arrival-date docket app calculations after a local convenience signal

HYPOTHESIS / PROTOTYPE: $4 is a proposed one-time price for filing the arrival-date docket, not a current sales offer. No measured time saving or buyer demand is claimed. The optional manual-retyping baseline above estimates one export’s retyping budget only; it does not change the calculation or guarantee savings.

Boundary and sources
Clock arithmetic only, not a verified itinerary, immigration check, jet-lag recommendation or arrival guarantee. Offsets are supplied by you and are not checked against a time-zone database. Confirm carrier times and destination clock rules with the carrier or travel provider before booking pickups or accommodation; allow separately for disruption and entry processing.
- Method: The tool subtracts the departure offset to obtain UTC, adds elapsed minutes, then adds the destination offset. The row displays the resulting destination date/time and the calendar-day shift relative to the entered departure label. The headline is the largest shift, not a sum across alternative legs.
- All sample records, dates, quantities and labels are invented. No outside policy, contract, rate, clock offset, measurement or accessibility standard is represented as verified.
- Google’s official pricing documentation, fetched 2026-09-30, says AI Studio is free in available regions. Optional formatting may require a Google account; manual local entry requires none. Limits can change and free-tier content may be used to improve products. Do not send private records.

Optional AI formatting, never the calculation
Manual entry completes this arrival-date docket for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.
Format only these fictional or non-sensitive notes for a arrival-date docket. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string"]}], "setting": "string"}. The columns are leg label | departure YYYY-MM-DDTHH:MM±HH:MM | elapsed minutes; the setting is Destination UTC offset in signed minutes. Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
