There can be several legitimate dates
A film can have a production period, festival premiere, television premiere and later repeat. A web page can add its own upload or update date. None automatically replaces the others. The date most useful to your question depends on whether you are studying the film, the event or today’s practical situation.
For a history documentary, earlier production may not reduce its value. For health, science or a changing public issue, the gap can matter substantially.
Look inside the programme’s context
Read the credits and official synopsis for production information. Note the period followed by the filmmaker and the dates of key interviews or events. An observational story may deliberately preserve a moment rather than claim to describe every later development.
A current schedule entry only says when the broadcaster plans to show it. It does not prove that the underlying research has been updated for that transmission.
Follow up according to the decision
For a school or research citation, record the title, creator and version alongside the relevant dates. For a present-day practical decision, consult the original institution’s current information or appropriate professional advice. Do not turn a general documentary into an individual medical or legal instruction.
When sharing a striking claim, keep the date and qualification attached. “The film reported this during its production period” is often more accurate than “this is happening now”. A powerful story can remain useful while its factual situation develops.
Make a four-line evidence note
Use four separate lines: what the programme shows, when those events occurred, when the film was produced or premiered, and when you watched it. Add “not stated” where a date is unavailable. This is more honest and useful than filling a gap from the schedule’s current year.
For example, a film may follow a community through a particular project and end before the project’s later outcome. Your follow-up should ask what happened afterwards, not accuse the original story of failing to know the future. A broadcaster’s later repeat does not necessarily claim otherwise.
If a page explicitly identifies an updated cut or postscript, keep that version detail. Otherwise, avoid assuming that a fresh website timestamp means new interviews or revised evidence. When comparing two versions, use running time and the stated edition as well as the title.

Does a repeat make a documentary useless?
No. Its value depends on the subject and your purpose. Preserve its time context.
Does a website update date prove the film was re-edited?
No. Look for an explicit statement about the programme version or updated content.
