How to: Auto Detect Outdated References in WordPress

It is no secret that outdated content can be quite a turnoff for your audience. Even if you have evergreen content, old dates can affect the performance of our posts. The good news is you can always write code to auto detect outdated references. Here is how:

This code scans your posts for date, time, and other references that could be outdated. It can send authors automated reminders every 6 months and displays warnings to admins as they edit outdated posts. It scans your posts using Regular Expressions patterns. It doesn’t change the content of your posts but that can also be automated.

This code adds a historical context widget to show original time references. It can flag content like “this year (year number)”.
