Date in Search Results - for pages cached after April 1

[kamikaze Optimizer]

I am noticing that if an article has a date in the article, such as news articles or blog posts do, that Google is posting that date as the first result in the search results.

This is only for pages that have been cached since April 1st (regardless of the date of the article).

...posting that date as the first result in the search results.

I'm not quite understanding the question. Do you mean that the date is appearing in the snippet? Or do you mean that the article is ranked first? If you're talking about regular Google serps, are you talking about the news results that appear above the serps, or in "site" serps themselves?

If you're talking about dates in the snippets, I've seen them when they're near words that are contained in my search query... but not all of these for pages cached after April 1.

Do you mean that the date is appearing in the snippet?

Yes, as the first thing in the snippet.

If you're talking about regular Google serps, are you talking about the news results that appear above the serps, or in "site" serps themselves?

The regular site results, not the news.
