A date-only announcement can acquire a clock time on a website. If a storage placeholder is set to midnight and copied into output, a visitor can read it as an announced start. K-POP PULSE’s event records contain a response that distinguishes an unannounced time.

I reread the historical code and fetched the current public event JSON and ICS. Fifty-six unannounced-time entries match date-valued calendar starts. One item in the same website’s structured data still supplies midnight, however. This account keeps the checked outputs and the remaining difference together.

A placeholder can become a promise to the reader

The registration guidance asks for a separate flag when no time was announced. It warns that omitting the flag can display an unsupported 00:00 KST. A timestamp used for storage or sorting is not necessarily an announced time a reader can act on.

Some releases really do announce midnight. Hiding every zero-hour value would lose those facts too. The relevant state is whether a time was announced, rather than the shape of its digits. Retain the known date and unknown-time state until a source establishes a time and its basis.

Pair the values distinguished by the current feeds

The fetched JSON and ICS each contain 89 events. I matched the 56 JSON entries with time_announced false to their calendar identifiers. Their time_kst values are empty, and each date-valued ICS start matches the supplied Korean date. Stored timestamps exist without becoming announced public clock values in those fields.

This is an actual HTTP response and value comparison, not a trial import into every calendar client or a guarantee for future events. A date-valued entry can help locate the day without establishing that the real activity lasts all day. That distinction belongs in the reader’s explanation as well.

Structured data on the same site still contains a difference

I compared the comeback page’s server-provided structured data with the event feed. One single-release entry has an unannounced time and an empty public time in JSON, while its structured startDate supplies the same day at 00:00:00 with a Korean offset. An output outside the visible page also needs semantic review.

Discovering this difference did not patch the original website. I have not tested its actual appearance in search results. For a property accepting dates or datetimes, an output condition can avoid adding an unannounced clock. Passing one feed check cannot establish that the other output paths are complete.

Make a small function that chooses by announcement state

The new teaching function below returns the date when time is unannounced and ignores a stored midnight proxy. If a time was announced, it checks an offset-bearing datetime against the supplied local date before returning it. A genuinely announced midnight remains a clock value under that explicit state.

Nine checks passed: eight synthetic conditions and one input shape drawn from the current recorded case. They cover format, flags, missing time and local-date mismatch. This is not an original-site patch, full event-schema validator or calendar-client automation. Connecting it to a website’s outputs is a separate implementation task.

def event_start_value(date_text,time_announced,local_start=None):
    if type(date_text) is not str or type(time_announced) is not bool:
        raise ValueError('Explicit date string and boolean announcement state required')
    day=date.fromisoformat(date_text)
    if day.isoformat()!=date_text:raise ValueError('Use YYYY-MM-DD date form')
    if not time_announced:return day.isoformat()
    if not isinstance(local_start,str):raise ValueError('Announced time requires a local datetime')
    instant=datetime.fromisoformat(local_start.replace('Z','+00:00'))
    if instant.tzinfo is None or instant.date()!=day:
        raise ValueError('Offset and local date must match the supplied date')
    return instant.isoformat()

Avoid an independent placeholder rule in every output

If page, API, subscribed calendar and structured data each reinterpret a stored timestamp, one can show a date while another invents midnight. A shared meaning based on date and announcement state, followed by format-specific conversion, leaves a clearer contract to review again.

Date-valued calendar starts and ends also need their format’s rules. An end date is not an inclusive last day. Nor does a date-valued representation establish the real event’s duration. Shared state helps, but the contract of each output format and the behavior of its consumers still require their own checks.

Move from unknown to confirmed when a later announcement arrives

Unannounced is not a state that must remain empty forever. A later time announcement can update it with the evidence for that change, followed by review of affected pages and subscriptions. Keeping the former uncertainty matters; the record should not imply the time was known from the beginning.

I do not present this account as a completed solution for every event representation. It retains the historical response, 56 current feed pairs, one structured-output difference and the narrow tests of a new function. Continuing to build a website requires preserving unknown information accurately, alongside adding information that becomes known.
