Rare Tijden is a free Chrome extension developed by Hay Kranen. This extension adds the sentence "Het zijn rare tijden." (It's strange times.) to articles on the largest Dutch and Flemish news sites. With just a simple installation, users can now see this unique sentence appended to articles on websites such as De Standaard, De Morgen, De Tijd, Het Laatste Nieuws, Het Nieuwsblad, and VRT.

The latest update, version 1.3, expands the reach of Rare Tijden to include Flemish news sites as well. Users in Flanders can now enjoy the same experience as their Dutch counterparts on websites like De Standaard, De Morgen, De Tijd, Het Laatste Nieuws, Het Nieuwsblad, and VRT. This update also brings the sentence "Het zijn vreemde tijden." (It's strange times.) to these sites.

In version 1.2, the extension now covers the regional sites of AD (De Gelderlander, BN/De Stem, Brabants Dagblad, etc.), ensuring that users on these platforms also experience the "rare tijden" phenomenon. Additionally, a bug that prevented the sentence from appearing on trouw.nl has been fixed.
