# Event calendar-time test card

Fictional exercise for [Check an event's time before someone adds it to a calendar](/learn/check-event-calendar-times). This companion and the guide are one piece. Expected answers below use the pinned 2026c baseline; they are not claims about current worldwide rules or a calendar provider's acceptance.

## Record the reviewed event

| Field | Your record |
| --- | --- |
| App/version and rule-data version | |
| Organizer local date and time | |
| Named zone | |
| Elapsed whole minutes, 1–1440 | |
| Candidate count and explicit earlier/later choice | |
| Reviewed UTC start and exclusive end | |
| Four dated local start/end displays with numeric offsets | |
| Reviewed UID and UTC revision stamp | |
| Saved filename and optional SHA-256 | |
| Actual result: pass, fail or unverified | |
| Evidence and next correction | |

## Eight fixed start cases

| Case | Organizer local start | Zone | Expected candidates, UTC |
| --- | --- | --- | --- |
| Ordinary | 2026-10-28 19:00 | America/New_York | 2026-10-28 23:00 |
| New York missing hour | 2026-03-08 02:30 | America/New_York | None; no export |
| New York repeated hour | 2026-11-01 01:30 | America/New_York | 2026-11-01 05:30 or 06:30; explicit choice |
| London missing hour | 2026-03-29 01:30 | Europe/London | None; no export |
| London repeated hour | 2026-10-25 01:30 | Europe/London | 2026-10-25 00:30 or 01:30; explicit choice |
| Half-hour offset | 2026-10-29 04:30 | Asia/Kolkata | 2026-10-28 23:00 |
| Sydney repeated hour | 2026-04-05 02:30 | Australia/Sydney | 2026-04-04 15:30 or 16:30; explicit choice |
| Sydney missing hour | 2026-10-04 02:30 | Australia/Sydney | None; no export |

The ordinary case lasts 60 minutes and ends at 2026-10-29 00:00 UTC. With a 90-minute New York repeated-hour event, the earlier candidate ends at 07:00 UTC and the later candidate at 08:00 UTC. Calculate elapsed duration from the chosen UTC start.

## Keep these results separate

| Test | Expected | Observed / evidence |
| --- | --- | --- |
| Blank, invalid or unsupported input | Unresolved; no substitution and no current export | Unverified |
| Repeated-hour choice | No preselected occurrence; timing edits require another choice | Unverified |
| 1 / 1440 minutes | Accepted; full date rollover shown | Unverified |
| 0 / 1441 / fractional / blank duration | Rejected | Unverified |
| Edit and revert after review | Prior current file cleared; review required | Unverified |
| Silent timing change before Review/export | Prior occurrence cleared before review | Unverified |
| Unicode, commas, semicolons, backslash and newline | Saved file decodes to the intended title and description | Unverified |
| Repeat download from one review | Same identity, stamp and bytes | Unverified |
| Failed or delayed copy/download | Honest status and visible text; edits cannot restore stale output | Unverified |
| Same-page navigation / actual leave or reload | Same-page inputs retained; actual leave/reload resets | Unverified |
| Keyboard and 390px phone | Labels, fold choice, focus and output usable without clipping | Unverified |
| Intended calendar parser/import preview | Record actual observed interpretation only when authorized and available | Unverified |

The exercise does not create an event, send an invitation or verify calendar interoperability. An import preview may lead to an event-creation action; do not treat that action as part of this card. A newly reviewed artifact after an edit cannot be assumed to update or cancel an earlier imported one.
