Make Google pick up mission dates in SERP

[SteveMarshall]

Looking at Google’s results for "apollo 13" -movie, Google appears to have detected dates for the first few entries. It would be really good if we could get dates like this on our search listings.

Notably, NASA History’s Apollo 13 “… a problem” page has “17 Apr 1970 ... came crackling over the radio from the Apollo 13 Command …” as its description.

For bonus points, individual transcript pages within the mission should be listed on the SERP with their start time.

We think this works by having something like [Launched/Updated/something] [date] (with optional punctuation) in the document.

It’s also worth noting that Google doesn’t officially document this behaviour, and there’s a hell of a lot of guesswork around SEO blogs about how/why this date appears. None of them are really sure, it seems.
