It’s common to present dates on the Web in a format such as "Published on September 12th, 2015", or "09/12/2015 09:41:23".
Each of these examples tells the full date and/or time of some kind of activity – be it a published article, or a reader comment, or perhaps an uploaded video.
Date formats like this might seem perfectly reasonable. After all, they’re informative and human-readable. Well yes, but “human-readable” doesn’t necessary mean users will readily be able to understand how recently the activity has occurred. The Web is a fast-moving place, and giving your content a sense of freshness could be the key to engaging with your audience.
